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:
- 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).
**User Error Handling:**
- [Sometimes, simply deleting and re-adding an action can resolve unexpected issues in Power Automate](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).
- [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.
