[BUG]: Error using local_json manifest: "Unable to download OS list"

[Cristian-Radiantis]

What happened?

I generated a local manifest using:

py create_local_json.py --online --capabilities usb_otg --device-capabilities usb_otg

This correctly creates:
os_list_local.rpi-imager-manifest

However, when trying to use this file in Raspberry Pi Imager (v2.0.7, Windows), Imager shows:

"Unable to download OS list. You can still use a local image file."

No OS list is displayed, only "Erase" and "Use custom image".

It seems Imager is not able to load the generated manifest and falls back to offline mode.

Is there any additional step required to properly use the local manifest?

How did you try to use the local manifest?

Hi! I tried both ways, directly opening the file which ends up opening the rpi imager and by directly opening from the settings in the rpi imager.
