I've a Flow which reads and email address from a List and then sends a canned message (Send Outlook v2).  The email address is well-formed but the Flow fails and complains that the email address is null.  I resubmit the Flow immediately and then it runs without a problem.

The below keeps happening to me.  I'm wondering if anyone has experienced the same thing?  Description:

    Sometimes Power Automate can have issues with caching which might be the cause.

     

    You're kidding, right?  Where can I find more information about this?  I mean which search keywords should I use to find posts/articles about this problem? @grantjenkins

    Can you try switching back to the classic designer and see if it works then. The new designer still has a few bugs - and I've seen this one a few times now.

    Alternatively, try re-adding a new Send an email action and try it again. Sometimes Power Automate can have issues with caching which might be the cause.
