Hi everyone,

So basically, everything was working fine on my app, and since yesterday i keep getting "The request was not sent or there was no response from the server. Check your internet connection. Error : [My List] null" each time my app uses a query to the sharepoint connector. I haven't changed my network since i got this error, so I'm pretty sure this doesn't come from my wi-fi.

Also, when I try to access my sharepoint site to create a new app or when I try to add a new sharepoint list to my app/refresh already added lists, i get an error too.

Thanks for your help 🙏

Building Power Apps

1. SharePoint Online Service Outage

Microsoft might be experiencing an outage that affects the SharePoint connector in Power Apps.

✅ Check Microsoft Service Health

Go to Microsoft 365 Service Health
Look for any SharePoint Online or Power Apps outages.
If there's an issue, you'll have to wait for Microsoft to fix it.

2. SharePoint API Throttling (Too Many Requests)

If your app is making too many SharePoint requests (e.g., frequent queries, Patch operations, or multiple users accessing at once), Microsoft may temporarily block requests.

✅ Try This:

Wait 15–30 minutes and try again.
Reduce unnecessary SharePoint calls in your app.
Try using delegation-friendly queries (e.g., avoid ForAll + Patch loops when updating multiple records).

3. Authentication Token Expired

Power Apps might have lost its authentication token to SharePoint.

✅ Try This:

Sign out of Power Apps (make.powerapps.com).
Close your browser.
Sign back in and refresh your connections:
- Go to Data → Connections.
- Find the SharePoint connection and remove it.
- Re-add the connection and try again.

4. Corrupt Power Apps SharePoint Connection

If the SharePoint connector is corrupt, it may stop queries from working.

✅ Try This:

Go to Power Apps → Data → Connections.
Delete the SharePoint connector.
Re-add SharePoint and refresh your lists.

5. SharePoint Site Permissions Issue

If someone changed SharePoint permissions, Power Apps may no longer have access.

✅ Check Permissions:

Go to your SharePoint site → Site Settings → Site Permissions.
Ensure your user account and Power Apps service account have at least Read & Edit access.
If using restricted SharePoint lists, ensure they are shared with your Power Apps users.

6. Browser Cache Issues

Sometimes, Power Apps can cache an expired session or outdated SharePoint data.

✅ Try This:

Open Power Apps in an incognito/private window.
If it works, clear your cache and cookies in your main browser and try again.

🛠 Final Debugging Steps

Test SharePoint Access: Try opening the SharePoint site in a different browser.
Test Another Power Apps App: If the issue happens in multiple apps, it's likely a SharePoint Online issue.
Check for Updates: If Microsoft has recently updated Power Apps or SharePoint, that might have broken something.
