Bug Report: Workflow Fails on Bulk Execution for Email Address Lookup
Hi Clay Support Team, I’m running into a bug when executing a workflow in bulk. What works:
If I run the “find email address” step cell by cell (one row at a time), it works reliably and returns the correct contact details.
The rest of the campaign/workflow also runs fine.
What breaks:
If I run multiple rows at once (even 2 rows), several rows unexpectedly change state mid-run.
Specifically, rows that should run suddenly behave as if the run condition is no longer met, so the step does not execute or stops populating outputs as expected.
After this happens, I have to rerun the affected rows, and only then the data gets created again and the rows can run normally.
Impact:
workflow does not work like this + burned credits due to failed or repeated executions
Here more details:
Could you help me understand why rows are changing state / run conditions fail during bulk execution, and what I should adjust to prevent this? Thanks!
