mail.inbox() Throws Because No Client Is Configured

Cause: The runtime did not call configureEmailsClient(...) before the flow ran. Check:
  • the runner creates the client
  • the runner configures it before flow execution

​
waitForMessage(...) Returns An Older Message

Check:
  • whether the flow should pass after: new Date()
  • whether the same inbox is being reused across multiple steps or retries

​
No Message Arrives Before Timeout

Check:
  • the product under test actually sent the email
  • the address being used is allowed for the workspace
  • the timeout is long enough for the expected delivery path
