Not specified by the original author.

TL;DR: Treat the 409 as good news: the event already exists, so fetch it by ID instead of creating it again. Then make the agent's retry logic expect the 409 and fall through to a read. Retrying a create with the same client-supplied ID will collide every time by design.

Google Calendar API 409 "the requested identifier already exists"

1. On receiving the 409, issue a GET for the event using the same calendar and event ID you sent. Expected: a 200 response with the event from the first attempt.
2. Change the agent's create path: catch the 409 and fall through to the GET instead of raising an error. Expected: retries return the existing event cleanly.
3. If the workflow genuinely needs a fresh event, generate a new unique ID per attempt rather than reusing the candidate-derived one. Expected: the create returns 201.
4. Audit the calendar for duplicates the earlier retries may have made under different IDs and remove them. Expected: exactly one event per interview.

Use this when

• A retried calendar-event create returns 409.
• The agent supplies its own event IDs for idempotency.
• Timeouts preceded the retry.

Not for this skill when

• The error is 403 rate limiting (back off instead).
• The error is 404 calendar not found (wrong calendar ID).
• The error is 412 precondition failed (etag mismatch).

Variant phrasings

• "Google Calendar duplicate event id"
• "409 already exists calendar event"
• "calendar event id collision retry"
• "requested identifier already exists"

Why it happens

The agent sends an explicit event ID for idempotency, the first request succeeds server-side, but the response is lost to a timeout. The retry replays the same ID, and Calendar correctly refuses to create a second event with it.

Edge cases

• Verify the fetched event's fields before reusing it; the first attempt may have stored stale details.
• Event IDs are unique per calendar, not globally; a 409 names the calendar it collided in.
• Deleting an event frees its ID only after garbage collection; immediate reuse can still 409.

TL;DR

Resolve the identifier clash in Google Workspace: a user, alias, or recently deleted account already holds that identifier, so restore or rename the existing account, or wait out the recently-deleted hold, before Terraform creates the new hire account. Prove it on one failing hire before rolling it to the rest of hires in the same sync or flow, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.

Terraform googleworkspace_user create failed "Error 409: the requested identifier already exists" for new hire account

Use this when

• You see this exact error or symptom: Terraform googleworkspace_user create failed "Error 409: the requested identifier already exists" for new hire account.
• The failure is in the provisioning path named in the title (HR source, identity provider, and target app), and it repeats on the same action rather than happening once and clearing.
• Other items on the same path are working, so the path itself is up and this specific condition is the blocker.

Not for this skill when

• A different error code, message, or tool is involved. Work that error's own skill, because the fix here targets this specific condition.
• The whole service or platform is down. Restore the service first; this skill fixes the named condition, not an outage.
• You cannot identify one affected item to test on. Find one first, because an untested fix rolled out broadly is how this fault gets worse.

Steps

1. Confirm the fault on one failing hire first and capture the evidence before changing anything: check the provisioning log entry for the one failing user in the identity provider (Okta system log, Entra provisioning logs, or the target app's SCIM log), and record the exact error text, the record or host involved, and the time it happened. Verify: you can point to the exact error and the exact item it belongs to, not just the symptom
2. Resolve the identifier clash in Google Workspace: a user, alias, or recently deleted account already holds that identifier, so restore or rename the existing account, or wait out the recently-deleted hold, before Terraform creates the new hire account. Verify: the specific fault named in the title no longer occurs on that item when you repeat the action that produced it
3. Make the operation idempotent: look the record up by its stable key before creating, adopt or update the existing record when it is the same entity, and log which path was taken. Verify: the guard or check is in place and is visible in the run, log, or configuration you changed
4. Retest end to end: rerun provisioning for that single user (on-demand provisioning or a sync cycle) and confirm the target account exists with the right attributes and status. Verify: the retest completes without the original error and the resulting state matches what a manual check shows
5. Roll the fix out to the rest of hires in the same sync or flow in the same way, watching the first few for the same error, and note the root cause and the change in the run or incident record. Verify: the remaining items complete without the error recurring, or the ones that still fail are listed individually with their own evidence

Compatibility: Okta, Microsoft Entra ID, Google Workspace, AWS IAM Identity Center, SCIM 2.0 targets and Terraform providers as named in the title.

Why it happens

This fault happens because create-style operations are not idempotent in most of these systems, so a retry or a pre-existing record surfaces as a hard conflict instead of a no-op. In this case the condition is the one named in the title, in the provisioning path named in the title (HR source, identity provider, and target app): the receiving or acting side reports the failure faithfully, but the underlying state (a record, a setting, a credential, a file, or a mapping) does not match what that action assumes. Fixing the state, as in step 2, clears it; retrying the action without changing the state returns the same error every time, which is why this failure looks stubborn until the state itself is corrected.
