    A few users are reporting similar issues recently. Please try to reauthenticate in your connections. If it doesn't work, remove the action and add it again (this is what worked for me when I got this issue a few days ago).
     
    Other solutions reported here in the Community include:
    - Recreate the flow
    - Open the flow in an incognito window
     
     
    Let me know if it works for you or if you need any additional help!
