Getting "Parameter "To" Cannot be null or empty". When flow hits my Send An Email step.

Posted on by

I am using Sharepoint Lists in order to have an approval workflow. Everything works fine but I added two actions to the tool. Once an item is created, send an email to the approver and create an event in their calendar. These two steps were created in Power Automate. Everthing worked perfectly until one day my flow stopped working. I am getting the following error:

 

Parameter 'To' cannot be null or empty.
clientRequestId: 5ca20b1b-b366-443c-80de-bf7c1c369655.

 

It seems Power Automate is not picking up the Approvers Email and it sees it as null or empty but in fact the email IS being provided by Lists. How can I fix this? Thank you! I had this problem once, I re-made my flow and fixed the issue. Now it´s happening again. Im looking for a permanent solution if anybody could please help.

    First of all, this forum is for Desktop flows, but based on your description, it seems like you are using Cloud flows. Cloud flow questions should be posted here: https://powerusers.microsoft.com/t5/Building-Flows/bd-p/BuildingFlows

     

    For what it's worth, in order for us to help you better, please provide some screenshots of your flow.

    Thank you.
