I'm building an automation that sends a message to a Slack channel when a user submits an onboarding form I created using Base44. The Slack message should include specific fields from the Base44 form.

The automation appears to run successfully. However, the Slack message does not include any of the form field data from Base44.

In the automation log:

  • The Base44 Entity Event trigger shows “Data Out,” meaning it's detecting the submission.

  • But the Slack Send Channel Message action shows no "Data In."

When I run a test, the automation works perfectly and includes the correct data. However, when someone actually submits the form, the Slack message lacks the expected data.

I’ve double-checked:

  • Field mappings - they are correct and use the latest test data.

  • The form fields - no recent changes have been made in Base44.

  • The Slack message action - it shows yellow warning icons next to the mapped form fields in its configuration.

I’m not sure why it works during a test but fails during real submissions.

Any suggestions?

 

 

Hi ​@Stella S. 

The screenshots shows mapped variables with warning symbols ( ! ).

That means either the variables are not mapped correctly and need to be remapped OR your need to test the Zap trigger step again to get an example record data for those mapped variables.

 

Hi ​@Troy Tessalone , I’ve already run the test several times on the trigger, making sure that I receive the latest record as test data each time. Everything works fine during test runs - I receive all the data in Slack. However, when I publish the automation and submit an actual response through Base44, the data doesn’t get sent to Slack.

​@Troy Tessalone here’s what it looks like on one of those test runs using latest record - no warning symbols at all
 

 

​@Stella S. 

Check your Zap Runs history details to see the DATA IN/OUT tabs.

If you need to, you can use an existing Zap Run as a trigger example:

Hi ​@Stella S., just checking in! 👋

Did you manage to get to the bottom of why the data from Base44 wasn’t appearing in the Slack messages? Was it that the fields needed to be remapped from a live Zap run, as Troy suggested?

Keen to make sure this gets sorted, so please keep us posted on how you’re getting on 🙂
