Fix invalid expression(s) for the input parameter(s) of operation 'HTTP_3'.

[Mgodby]

Hello. I am trying to do a POST Http request based on what's on this documentation: https://docs.microsoft.com/en-us/graph/api/application-post-calls?view=graph-rest-1.0&tabs=http#perm...

I'm attempting the Example 5.

When I first pasted the JSON body, it said the JSON was invalid but that was only because there was an extra comma after preFetchMedia:

After removing the comma, I pasted the body into my http request:

Then the "Fix invalid expression(s) for the input parameter(s) of operation 'HTTP_3'." error appeared. I noticed that if I remove the "@" symbol from the @odata.type fields the error goes away but I'm worried that that might be breaking things.

Does anyone know what's wrong with this and how to fix it? Thank you.

Hi @Mgodby 

I had that problem the other day, and it took me some time to understand what to do.

In the "@odata.type," put "@@odata.type". It will pass the validation and return the result you want

Can you please check if and let me know if you have any questions?

I got it to work by doing a compose with "@odata.type" within it and then referencing that in the http body.

agree that adding additional @ to the @odata.id property name does work. Stupid this isn't necessary when using the HTTP Azure AD action. Custom connector Body also requires the additional @. This must be a bug?
