Page crash after attempt to generate config/QR for user with no permission

[teon]

@almulalic could you share any details about the configuration so we could replicate/try to. find what's wrong? If you don't want to post them here publicly you can email us at: [email protected].
We need:

• name of the VPN
• name of the device
• first, ast name & username of the user for which the device was configured
• VPN server IP
• port
• VPN network address

Also can you go to the "core" logs and post them?

Based on that we will replicate and have the ability to fix.

Sure, I can publish it here. I managed to get a video for this which I sent to support email.
Most of the questions are answered in the video, however I can't share the IP and port.

However I could share my deployment info:

@almulalic from what I see you are not using official release images (sha-xxx). That may be the case.

Can you user 0.9.0 image tag (latest release)?

[almulalic]

Tried to migrate but got some SQL migration errors which are fine for now as I used this cluster for testing. I created a fresh new database with the :latest tag on core and the same issue still persists.

1. Create a network
2. Assign it to admin group
3. Create a new user that doesen't have admin group
4. Log in as the user, go to add device and go through the wizard
5. Wizard will crash after the key setup
6. (Optional) go back to his profile, same behaviour is present on Show configuration option
7. Go back to admin account
8. Add admin group to user
9. Go back to user
10. Show configuration should work now and the wizard for adding new devices should complete

Also the behaviour should be present when you visit https://domain.com/add-device and refresh the page.

The code is minified so I didn't get much info from digging through references in console, but the error is same

[almulalic]

Also, I tested out the scenario where there are 2 locations one is admin only and the other one is public so it seems that as long as there is one location that user has access to everything works.

My best guess would be that QR code generation is done under the assumption that there is at least one network/location, and then when 0 networks are returned it tries to find property netowrkId on nothing.

@j-chmielewski I've replicated this on our DEV:

1. New account (not admin)
2. Logged in to this account
3. Added a new device
4. Named the device -> NEXT
