agent hallucinating tax classification not in source data for validate vendor

Not specified by the original author.

TL;DR

Fix this in 1099 validation agent by acting on the exact problem first: require the agent to base the classification only on the entity box actually checked on the signed W-9, record which box was checked as its evidence, return classification unknown when no box is clearly checked, and route unknown cases to a human instead of letting the agent infer a type from the vendor name. Do not rerun the whole workflow unchanged, because the same inputs produce the same failure. Prove the fix on one vendor first, then rerun the full scope and reconcile the results.

agent hallucinating tax classification not in source data for validate vendor 1099 classification error hallucination failure

Use this when

• The operation in 1099 validation agent fails with this exact problem: agent hallucinating tax classification not in source data for validate vendor 1099 classification.
• The same failure repeats on retry with unchanged inputs.
• A vendor onboarding, payment setup, screening or vendor record step is blocked until this is resolved.

Not for this skill when

• The notice is a platform outage from the vendor of the tool. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with a commercial decision such as price or terms. That is a negotiation, not this failure.

Steps

1. Reproduce the failure on one named vendor in 1099 validation agent and record the full problem text plus the vendor, supplier record or onboarding case involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: require the agent to base the classification only on the entity box actually checked on the signed W-9, record which box was checked as its evidence, return classification unknown when no box is clearly checked, and route unknown cases to a human instead of letting the agent infer a type from the vendor name. Verify: the single failing vendor now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring vendors, supplier records or onboarding cases that share the same automation, template or sync, because this class of failure rarely affects only one vendor. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in 1099 validation agent on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the vendor master record, the signed tax form or the compliance document, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the vendor record so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

How to fix - agent hallucinating tax classification not in source data for validate vendor 1099 classification error hallucination failure

The how to phrasing for the same failure in 1099 validation agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

1099 validation agent troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

A vendor name ending in a company suffix invites an inferred classification, and an agent that infers instead of reading the checked box files vendors under a type their own form never claimed.

Edge cases

• The vendor was merged, renamed or given new banking details after the failing run started. Refresh the vendor state and reapply the fix against the current values, not the values from the failed run.
• The single vendor proof passes but the full rerun still fails on other vendors. Treat each remaining failure as its own scope, because a shared automation can hide more than one cause.
• The source systems disagree on the correct value. The vendor master record governs identity and payment details, the signed tax document governs classification and withholding, and the compliance screening governs approval status; record which source won and why.

Compatibility: 1099 validation agent at current versions, plus the procurement, ERP or screening platform the query names; no extra tooling beyond access to the source records needed to verify results.

Fix this in Coupa onboarding agent by acting on the exact problem first: require every figure and date in the onboarding to come from a retrieved source, the W-9 for tax details, the bank letter for account numbers and the agreement for terms, add a check that compares each loaded value against its source document, and remove any loaded value that has no matching source before submitting the supplier.

Coupa onboarding agent troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

When a lookup or a parse returns empty, an agent can fill the gap with a plausible value, and only a field by field comparison against the source documents separates real supplier details from invented ones.

Edge cases

• The vendor was merged, renamed or given new banking details after the failing run started. Refresh the vendor state and reapply the fix against the current values, not the values from the failed run.
• The single vendor proof passes but the full rerun still fails on other vendors. Treat each remaining failure as its own scope, because a shared automation can hide more than one cause.

ERP vendor creation agent troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

Creation forms with many empty fields invite an agent to complete them plausibly, and a read back comparison against the approved request is the check that catches invented terms, addresses or contacts.

Edge cases

• The vendor was merged, renamed or given new banking details after the failing run started. Refresh the vendor state and reapply the fix against the current values, not the values from the failed run.
• The single vendor proof passes but the full rerun still fails on other vendors. Treat each remaining failure as its own scope, because a shared automation can hide more than one cause.
