Can you please provide the detailed steps in your flow? I will try to reproduce your issue after you offer more information. Please show the trigger, the detailed info about your condition and actions.
Also, try to recreate the flow to test.
I'm also getting the same error plus a second error which appears to relate tot he first email having an error..
Email 1 error:
I also experienced the same problem with the 'Send an email' action.
Though I found a solution!
I did see something about an error regarding an 'authentication token has expired' before receiving this issue, after I added the 'Send an email' action to the workflow. The error appeared above the action, but has since disappeared. My guess was that the error was still valid, but the display message for the error has disappeared.
You can resolve this by:
Navigate to your 'Send email' action, and click the '...' > 'My connections' > 'Add new connection'. When I had this error, it was because I had to re-authenticate whatever token is required to sustain the connection. By adding a new connection, it was re-authenticated and emails were successfully sent.
Be sure to check the correct email inbox as well, especially if you are using a demo user rather than your regular inbox.
I am also experiencing this error, but with the "Create an event" action for Google Calendar. I tried re-authorizing with no luck. Any other ideas?
Oh wait, I think I was misunderstanding and thought it was an error with the action itself, but I think I messed up my condition (checking category "equals" Blue category, instead of category "contains" Blue category).
Did you ever find a solution to this issue? I am trying to send an email if a condition is equal to Yes as well. It seems to accept the condition but then stalls on that email.
