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:

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 error message:

Parameter 'To' cannot be null or empty.

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.
