Publishing a flow in the cloud appends ['output']

There is a critical bug when publishing a flow in the cloud version. Every time I click ‘Publish Flow’, the platform appends an extra ['output'] string into existing data tokens (e.g., turning {{trigger.data}} into {{trigger['output']['data']}}). If I publish 3 times, it nests it 3 times. This happens automatically to all pieces in the flow without modifying them. This happens with Firefox as well as with the ZEN Browser. So it is not a browser issue. It seams not to happen with the first publish. the work around is to export the flow, delete all ['output']import it again.

Hi @ManfredWahl

Escalated to the engineering team, They are taking look right now.

please don’t delete the flow you created, and please send us the flow you were using, was it this ?

also can you please confirm what is the url you are using ? it was cloud.activepieces.com and NOT canary.activepieces.com

This appears to match Activepieces PR #13571:

“Data mapping between steps is broken on main for many existing flows — even with small payloads.”

Our symptoms:

  • Previously stable webhook-triggered flow began failing without intentional lookup-step changes.
  • Webhook body contains valid body.run_id.
  • Hard-coded Tables filters work.
  • Dynamic mappings from webhook/code-step outputs resolve as undefined/empty.
  • Code-step inputs mapped from prior Tables outputs sometimes arrive empty even when upstream step returns rows.
  • Duplicating the flow did not repair the issue.
  • Tables Find Records fails with: “Invalid input: expected string, received undefined.”

Please confirm whether our cloud workspace/flow has been affected by the v22 step-output-nesting migration or the cloud publish bug that appends/nests [‘output’] into tokens.

Please also advise whether we should:

  1. wait for the engine fix to deploy,
  2. export/import after the fix,
  3. manually rewrite mappings to the new {{step.output…}} form, or
  4. avoid publishing until the cloud publish token mutation bug is resolved.

I am on cloud.activepieces

yes - it is cloud.activepieces.com. Nevertheless the issue is resolved. It seams that there has been an software update over the weekend, which caused many issues. Now the cloud version is fine again.
