HTTP Request Error - Property does not exist on type

I'm building a flow that needs to send an email from "" This can be done with the " Send HTTP request to SharePoint" command. I've built one other flow that uses the same basic JSON. It works fine in the other flow, but here it is hitting an error: 

Here is what the relevant part of the code looks like. 


Like I said, there's no problem running it in another flow that interacts with the same SharePoint site. But in this flow, it gives me this error: 


Obviously the property does exist on __metadata, because this code block is cut and pasted from somewhere else where Power Automate has no trouble finding the property on type. Does anybody know what could be going wrong here?

Are you sending header as application/json. Sample below.


{ "accept": "application/json;odata=verbose",
                   "content-type": "application/json;odata=verbose",
                   "X-HTTP-Method": "MERGE",
                   "If-Match": "*",
                   "X-RequestDigest": "__yourRequestDigest__"}

 Also which method are you using in HTTP? Is it Post OR Get? 


Can you please provide screenshot of actions from both the flows?
