I use a "compose" in my flow and it's function is to get the body of a excel I input in up flow, when I do a test, there is some issue with the compose, there is no input and output there, just like what looks like in the picture, there seems some bug with the compose. When I click show raw inputs, there is only a url in it and there is nothing with the url.

Hi @XX-20120238-0,

It looks like your Compose has a null value (aka the value is empty). Can you share a screenshot of your code view tab? This will help troubleshooting where this null value is coming from.

Below is an example which shows the same behaviour when I use a null value in a Compose action.

Same outputs

@Expiscornovus I had already solve that problem, I think it's a bug with power automate, the title of the body where I try to get there is a space at the end of the title, this will cause this error, and when I delete the space at the end of the title, the process worked will, now I meet the same problem with another condition just like this. There is no space at the end of the title, but it still an error.
