agent hallucinated a fivetran connector id that does not exist, sync check

Not specified by the original author.

TL;DR

Connector ids in Fivetran are opaque generated strings, and an agent asked for one it does not actually know will often produce a confident, well formatted, nonexistent id. Any call with it then fails with a not found style error that looks like a Fivetran problem. List the connectors in the group through the API, match by the connector name and service you intended, and use only an id returned by that list. Never let the agent proceed on an id from memory or from a naming guess.

agent hallucinated a fivetran connector id that does not exist, sync check failed

Use this when

• A sync status check fails saying the connector does not exist or is not found.
• The connector id in the agent's config or message was never copied from the Fivetran UI or an API response.
• The named connector clearly exists in the dashboard under a similar name.

Not for this skill when

• The id came from an API list response and the connector was since deleted. Recreate or repoint deliberately.
• The call fails on authentication. A valid id with a bad credential fails differently; check the error wording.

Steps

1. Capture the failing call: the connector id used, the group it was sent to, and the exact error. Note whether the error is not found versus unauthorised. Verify: the failure is classified before any new id is trusted
2. List connectors for the group through the Fivetran API and search the result by service and schema name for the connector you meant. Note the real id from the response. Verify: the id now comes from the system of record
3. Compare the real id with the invented one and check every place the invented value was written: agent config, a runbook, a ticket, a script default. Note each place to correct. Verify: the bad value is hunted down everywhere it spread
4. Replace it, rerun the sync check, and confirm Fivetran returns the connector state for the real connector. Note the state and the last sync time it reports. Verify: the check works against the real connector
5. Change the workflow so ids are always resolved at run time: the agent lists connectors, matches on name, and refuses to call a per connector endpoint with an unresolved id. Note the guard in the procedure. Verify: an invented id can no longer reach the API

Variant phrasings

fivetran connector not found api wrong connector id

The plain API error phrasing.

fivetran list connectors api get connector id by name

The resolution method searched directly.

Compatibility: Fivetran REST API, connector and group resources. Applies to any agent or script that addresses Fivetran objects by id.

Why it happens

Generated ids are the worst case for a language model: they carry no meaning to memorise, their format is easy to imitate, and a request that names one confidently gives no signal that it was fabricated. The system on the other end cannot help either, because a nonexistent id and a typo look the same to it. Grounding has to happen by construction: resolve names to ids through list endpoints in the same run, and treat any id that did not come from a tool response in this session as unverified.

Edge cases / pitfalls

• Two connectors can share a service and a similar schema name in one group. Match on more than the first hit: destination, schema, and creation context.
• An id copied from a different Fivetran account or a test group is real but wrong. The group is part of the identity, check both.
• Screenshots and old tickets are common sources of stale ids after a connector is recreated. Prefer a live list over any document.
• If an agent wrote the invented id into a shared config, assume other automations picked it up. Search the repo and the runbooks, not just the failing job.

TL;DR

The agent compared the last sync time against the wrong expectation: the connector's schedule, its pause state, or its typical duration. Read the connector's configured schedule and pause state first, then judge the last sync against that. A sync that ran six hours ago on a daily schedule is healthy, not failed.

agent mis-read fivetran sync schedule and flagged a failed sync

Use this when

• An agent flags a Fivetran sync as failed when it is healthy.
• The agent assumed a frequency the connector does not have.
• Paused connectors get flagged as broken.

Not for this skill when

• The sync genuinely failed. Read the sync error.
• The schedule itself is wrong. Fix the schedule.

Steps

1. Read the connector's configured sync frequency and pause state. Note the expected cadence. Verify: the expectation is grounded
2. Compare the last successful sync time against the cadence, allowing normal variance. Note the comparison. Verify: healthy versus late is decided fairly
3. Fix the agent's check: schedule-aware, pause-aware, variance-tolerant. Note the new logic. Verify: the check reads reality
4. Add test cases: paused connector, daily cadence, recent success. Note the tests. Verify: the cases are pinned
5. Verify the agent stays quiet on a healthy connector. Note the silence. Verify: the false alarm is gone

Variant phrasings

fivetran sync schedule check

The monitoring-shaped search.

fivetran paused connector monitoring

The pause-shaped phrasing.

Compatibility: Fivetran dashboard and API for schedule and sync history. Agent check logic is yours to write.

Why it happens

Monitoring without schedule context is just anxiety: every connector has its own cadence, and paused is a valid state, not a failure. Agents that hardcode hourly expectations flag daily connectors as broken every day. The schedule is part of the connector's definition of healthy, so the check must read it. False alarms are expensive twice: they wake people up, and they train people to ignore the monitor, which is how a real failure later goes unnoticed.

Edge cases / pitfalls

• Frequency changes take effect on the next cycle. A check run during the transition sees a confusing gap; allow for it.
• Manual syncs between scheduled ones reset the last-sync clock. The check should consider any successful sync, not just scheduled ones.
• Connectors blocked on setup or schema approval are neither paused nor healthy. Classify blocked as its own state.
• Timezone differences between the agent and the dashboard can shift the comparison by hours. Compare in UTC.

Check Fivetran connector setupstate and syncstate before trusting its data

TL;DR

Before trusting any Fivetran connector in automation, check status.setupstate == connected. Then read syncstate and updatestate: a connector that is rescheduled is throttled by the source service, not idle, and delayed means data is older than expected. Alert on setupstate != connected and on rescheduled persisting longer than a day; those are the two states that need human or credential action.

Use this when you run into the situation in the title.

When not to use this skill: unrelated tasks. It covers only the procedure above.

Compatibility

The steps above apply to the commands named in them. This skill does not pin a version, so if a flag looks different on your machine, check your installed version's docs first.

Details

Context: Real-world Fivetran notes (fields documented in the terraform-provider-fivetran data source docs): a connector is only healthy when setupstate is connected. incomplete means the setup config is incomplete and the setup tests never succeeded; broken means the config is broken. Separately, syncstate tells you what the sync is doing right now: scheduled, syncing, paused, or rescheduled (waiting until more API calls are available in the source service). updatestate is onschedule or delayed. Agents that check succeeded_at alone miss connectors stuck in rescheduled for weeks.
