Boolean variable inside Condition is seen as 'string' rather than 'boolean'.

I'm getting a weird error from Flow inside a condition. I'd appreciate any insight people can give me.

The left side of my condition, which is set as a boolean variable, is being evaluated by Flow as a string value. Before the variable, I was checking for empty() on the left side of the condition with the same result. I've used similar syntax successfully in other Flows.

empty(variables('ContactId'))

Can you show a screenshot or paste in the code behind the IfContactIdExists condition? If the value is coming in as string, you can easily convert it to boolen by wrapping it in bool(), example:
bool(true)

It is simply my boolean variable:
variables('ContactExists')
Before that, I was checking empty() on the id, which also returns a boolean.

I just discovered that the "if yes" path of my condition works fine. I'll delete the "if no" actions and redo it. I can try the bool() option if all else fails. Thanks.

Hi @Anonymous ,

Could you provide screenshots of Create a new record action configuration and the details of if() function configuration?

I did a test on my side. If I configured a Boolean variable in if() function, there would be no similar error.

Please take a try.

Best Regards,
