403 Error with Event endpoints

Hello:

I filed a case with Blackbaud, and they told me to try to Developer forum, since they believe the problem lies in the Power Platform and not the SKY API.

I am attempting to build a flow that will add participants to an event. When I try to contact any event endpoint in the production environment, I get a 403 error. I don't get this error in the Sky Developer Cohort, or when using the Try It console against production.

This is just one example connector. I also get the same error with any of the Event connectors I try, such as Updating an Event, listing Events, or Querying a Specific Event.

And here is an example JSON response:

{
"statusCode": 403,
"headers": {
"Cache-Control": "no-store, must-revalidate, no-cache",
"Strict-Transport-Security": "max-age=31536000; includeSubDomains",
"Request-Context": "appId=cid-v1:0c37065f-4d7c-47cf-af06-96cd9a75949d",
"X-Content-Type-Options": "nosniff",
"x-ms-function-status": "OK",
"Date": "Sat, 20 Apr 2024 00:25:19 GMT",
"Content-Length": "0"
}
}

Does anyone else have this issue? I have seen the posts where some people are getting this error with Static Queries endpoints.
