I have a power automate flow that has been running for a few years now and it all of a sudden is getting the following error:
Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256
Failed to validate token: IDX10249: X509SecurityKey validation failed. The associated certificate has expired. ValidTo (UTC): 'System.DateTime', Current time (UTC): 'System.DateTime'.
Any suggestions as to why this is happening?
