I need help in fixing this error: "the data return in the response is invalid, response data should be a valid json object error"

I get this error when trying to generate and send a PDF file to an email address / When trying to save the PDF file to a Document Library.

The action completes and i receive the PDF file just as expected, however this error comes up.

Is this an known error? or am i making any mistake.?

I am trying to generate a PDF file of a Container and share the same on email.

With my initial flow, it creates a file and also generates an email with the same. Task is successful, but the error pops up.

Hi @Anonymous ,
From your screenshot, what went wrong is some issue with the trigger
Please try to delete the trigger, add it again, and use it again after refreshing.

I am not sure what is the issue. I had a PDF viewer (Experimental) on the screen, i removed it and now everything works fine. I don't get that error anymore.

but thank you for your support @v-chengfen-msft
