Token Exchange Error

Posted on by 2
Hi everyone,
Our company has multiple flows that are quite simple. Whenever someone filled in a response in Microsoft Form, we have a flow that get the response and emailed those response to the specific email address.
Recently all the flows failed with the following error:
 
Action 'Get_response_details' failed
 
Error Details: 
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): '8/27/2024 11:59:59 PM', Current time (UTC): '9/11/2024 1:48:56 AM'.
 
 
On the flow it self has the following details:
 
{
  "status"400,
  "source""https://australia-001.token.azure-apim.net:443/tokens/australia-001/microsoftforms/shared-microsoftform-xxxxxxxx-xxxx-xxxx-xxxx-xxxx-xxxxxxxx/exchange",
  "message""Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256\r\nFailed to validate token: IDX10249: X509SecurityKey validation failed. The associated certificate has expired. ValidTo (UTC): '8/27/2024 11:59:59 PM', Current time (UTC): '9/11/2024 1:48:56 AM'.\r\n"
}
 
I know that it can be fixed by exporting the flow and re-importing it but we have 40+ flow to do it for every single flow. We also wants to make sure that it doesn't happened again.
Is there a way to fix this or preventing this from happening?
Appreciate your help.

    HI
     
    Can you refresh the connection, make sure its valid, since under the covers this is where it matters.
     
    I'd hate to have you have to create new connections (which is time consuming) OR deleting your flows and starting over.
     
    Sorry this is happening :-(
