Partner Centre Certification Process

Hello Team

We are following the new process however there are a few issues we cannot circumvent:

1. We cannot add our connector to a Power Automate solution to verify using the solution checker due to the following error: The request failed with error: '{"error":{"code":"0x80044331","message":"A validation error occurred. The length of the 'openapidefinition' attribute of the 'connector' entity exceeded the maximum allowed length of '500000'."}}'.
2. We cannot use paconn either as it is generating the following error upon validation:
   HTTPSConnectionPool(host='api.powerapps.com', port=443): Max retries exceeded with url: /providers/Microsoft.PowerApps/objectIds/71b6b311-8a5e-4e52-88c6-07e0e1301290/validateApiSwagger?api-version=2016-11-01&enableConnectorCertificationRules=true (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:2384)')))
3. We cannot use paconn download, as after selecting the environment the following error occurs:
   {
   "error": {
   "code": "InvalidAuthenticationToken",
   "message": "The received access token has been obtained from wrong audience or resource."
   }
   }
   401 Client Error: Unauthorized for url: https://api.powerapps.com/providers/Microsoft.PowerApps/apis?api-version=2016-11-01&%24filter=environment****redacted****

Can you advise please?

Start with the three failure reports in the issue: the Power Automate solution checker limit, paconn validation SSL error, and paconn download authentication error. Reproduce the affected certification steps if possible, then document a verified resolution or the precise external blocker for each failure.
