Empty payload. JSON Expected Graph API

Posted on by Braaank

Hello,

I have created a custom connector for testing and I cannot get it working with POST methods.

The weird thing is that if I test the custom connector from the configuration it works, but when I'm trying to test the method through clicking a button in PowerApps I've got the following error message:

This is what I received when testing the custom connector:

I was having a similar issue with the header "Content-Type" and I had to create a policy in order to set it.

Am I missing something here?

Thank you in advance.

Re: Empty payload. JSON Expected Graph API

Hi, I was able to fix this replacing the formula. It seems that the column
'fields.Title' is not valid, as it is not the same as putting

GraphAPICustomConnector.CreateSpItem({fields:test})

Where "test" is a varible that's been set like this:
Set(test;{Title:"test"})

Re: Empty payload. JSON Expected Graph API

You could try to use the JSON() function on the record argument, that way at least you can force it.
Also, if you trace the call with the browser development tool, you can see what happens 😉
