    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!

    Yup, I tried but didn't work. I got a solution that if we will come back to old designer then this become fixed.

    When using the new designer, reauthenticating the connection did not fix this issue. Removing and adding the action did not fix the issue. The two things that worked for me. Disabling New Designer worked for me. If you want to keep New Designer on, creating a completely new workflow fixed this issue for me.
