"Parameter 'Folder Path' cannot be null or empty" on a simple flow

Question

I created a simple flow where I alert when an important email is directed to me and for some reason the error mentioned in the title occurs. Does anybody know how to solve this?

Hi @José Junior,

Thank you for reaching out to Microsoft Q&A forum!

Certainly! The error message “Parameter ‘Folder Path’ cannot be null or empty” typically occurs when a required parameter is missing or contains no value. Here are a couple of possible solutions:

Check the Flow Configuration:

• Verify that you’ve correctly configured the flow, especially the “Create file” action (if you’re using it). Ensure that the “Folder Path” parameter is set to a valid value.
  • If you’re using OneDrive for Business, browse to the correct folder path in the “Folder Path” parameter1.
    • If you’re using SharePoint, make sure the folder path exists and is accessible.
    Data Availability Timing:

    - If your flow is triggered by the addition of an item to a list, ensure that the necessary data (such as the UPN) is available before the flow executes.
    
       - [Avoid adding multiple items simultaneously in grid view, as SharePoint processes them immediately, potentially triggering the flow before all data is available](https://powerusers.microsoft.com/t5/General-Power-Automate/How-to-specify-Folder-Path-parameter-including-non-ascii/td-p/2150199)[2](https://powerusers.microsoft.com/t5/Building-Flows/Parameter-To-cannot-be-null-or-empty-but-it-s-not-empty/td-p/1504514).

             - [Consider saving a new copy of the flow if other troubleshooting steps fail](https://powerusers.microsoft.com/t5/Building-Flows/Parameter-To-cannot-be-null-or-empty-but-it-s-not-empty/td-p/1504514)[2](https://powerusers.microsoft.com/t5/Building-Flows/Parameter-To-cannot-be-null-or-empty-but-it-s-not-empty/td-p/1504514).
    

Remember to thoroughly review your flow configuration and data availability to pinpoint the cause of the error.
