Mobile: Cannot Upload Extension (No Response / Error)

GDevelop general Bugs reports
1

Hello,

I’m having an issue uploading a custom extension file in GDevelop from a mobile device.

When I select the extension file (JSON format) and press the upload button, nothing happens at all—no loading, no error, just no response.

I tested this on multiple mobile browsers:

  • Samsung Internet → no response at all
  • Firefox and Brave → I get this error:
    “An error occurred while loading this extension. Please make sure the extension file is valid and compatible with this version of GDevelop.”

Additional details:

  • I’m using the latest version of GDevelop in the browser
  • The extension file is valid and correctly structured
  • File size does not seem to matter (same behavior regardless of size)
  • The same type of file uploads normally in other contexts

This makes me think the issue is related to mobile browsers or how file uploads are handled on mobile, not the file itself.

Is this a known limitation, or is there any workaround to upload extensions from a phone?

Thanks.

Thank you for reporting.
I can confirm I reproduced the issue on browsers like Firefox and Samsung one.

We’ve implemented a fix that will be available in next release : Fix file uploads on web browsers like Firefox by ClementPasteau · Pull Request #8531 · 4ian/GDevelop · GitHub

In the meantime, using Chrome should work.
