Trigger Condition not working when combining not and equals

Dear Pros,

I am trying to use the following trigger condition

@not(equals(triggerBody()?['StatusOfDocumentationOld'],triggerBody()?['StatusOfDocumentation']?['Value']))

to compare to values and only fire when they are not equal.

However, I am always getting

Unable to get property 'properties' of undefined or null reference

as an error message. Both values exist and once I remove the not from the condition, it works fine...

Any idea what I am doing wrong is highly appreciated.

Many thanks!

Christian

Hi @anatius007 ,

I used the same expression on my side for testing. When I saved Flow, I didn't encounter similar problems.

Maybe you can try the following expression:

@equals(equals(triggerBody()?['StatusOfDocumentationOld'],triggerBody()?['StatusOfDocumentation']?['Value']),false)

Hi Barry,

Thanks for your suggestion, but your proposed expression gives the same error message as my original one...
Any other ideas?

Hi @anatius007 ,

It's strange that these trigger conditions work fine on my side.

Have you tried re-creating the Flow and updating the connection?

Or use other fields to test the not() function.

Besides, you could consider using Condition instead of trigger conditions.

Best Regards,
