Error Saving Canvas App

Posted on by ali.mimbisa

Good day. Last night I notice I keep getting errors when saving my canvas app and until now I still experience it from time to time.

I tried deleting the app and importing it again. For a moment it saves, works normally and then it stops working again after some time.

I also tried creating from blank/scratch, still the same, it will not save after some time.

This is the complete error:

Error saving to document server. Code: failedToPutApp Error: {"error":{"code":"ServerTimeout","message":"The request timed out. The correlation Id is '39323e62-5431-4487-a8cc-569a2615c75e'."}}

Hi,

The issue you're experiencing, where your Power Apps canvas app fails to save with a "ServerTimeout" error, could be caused by several factors. Below are potential troubleshooting steps and solutions:

1. Investigate Server Timeout Causes

Large App Size:
If your app has many screens, data sources, or heavy media usage, it may exceed Power Apps' server processing capacity during save operations.

Solution: Minimize app size by reducing unused media, compressing images, or breaking large apps into smaller components.

Data Source Issues:
Timeouts can occur if Power Apps tries to validate or interact with data sources during the save process.

Solution: Disconnect unnecessary or unused data sources temporarily and attempt to save.

2. Clear Browser Cache and Try Incognito Mode

Cached files or browser extensions might interfere with Power Apps' saving functionality.

Steps:

Clear browser cache and cookies.

Use incognito/private mode to test.

Use a different supported browser like Microsoft Edge or Google Chrome.

3. Check for Service Health Issues

Power Apps backend services might be experiencing temporary outages or performance degradation.

Action:

Visit the Microsoft Power Platform Service Health page to check for ongoing issues.

If there’s no reported outage, report the issue with your correlation ID to Microsoft Support.

4. Optimize Save Operations

Avoid Concurrent Edits:
If multiple users are editing the same app, conflicts can cause save failures. Ensure only one person edits at a time.

Save Frequently:
Save changes frequently to reduce the risk of timeout errors during large operations.

Use Save As:
Instead of saving, try File > Save As to create a new version of the app. This sometimes bypasses server validation errors.

5. Review Network Conditions

Ensure your internet connection is stable and fast (minimum 1 Mbps recommended).

Test saving on a different network to rule out local network issues.

6. Split Complex Apps

If your app is highly complex:

Break it into smaller apps or modules to reduce save complexity.

Use navigation links between apps for a modular approach.

7. Report to Microsoft Support

If the problem persists:

Open a support ticket with Microsoft.

Provide the error details, correlation ID (39323e62-5431-4487-a8cc-569a2615c75e), session ID (f724fa87-8500-47d1-93a5-4020a3ac896b), and steps to reproduce the issue.

Immediate Workaround

Export the app (File > Save As > Download a copy) after making changes to ensure your progress isn’t lost.

Retry saving later, as backend issues may resolve on their own.

Hi ali.mimbisa

The most likely cause of a "ServerTimeout" error would be a poor internet connectivity, or a slow network.

If it's only been happening for a day, this could be a one-off issue. Hopefully this issue might resolve itself if you give it a few days.

I can confirm , I am having the same issue starting from 1st Jan,2025 . It was working earlier perfectly. I am not able to publish and save. This is a real blocker. It would be good if someone can look at it .

@VASANTH KUMAR BALMADI I looked into your suggestions and none of them worked for me, this app was last saved on end of december. I was able to save it that time.
