Cannot switch to PUI - `None` shown in browser

[Keybored02]

Please verify that this bug has NOT been raised before.

• [x] I checked and didn't find a similar issue

Describe the bug*

When prompted to switch to PUI during login, if link is clicked no UI is loaded. This is not affected by the browser or machine accessing it. It happens with inventree.localhost too, with and without SSL certification. No error report is shown in the admin console. Unsure where the log files are located with DEBUG disabled.

Steps to Reproduce

1. From the login screen, click the link to PUI switch.

Expected behaviour

The UI is switched from CUI to PUI, as in the demo. A new login page appears.

Deployment Method

• [ ] Docker
• [x] Package
• [ ] Bare metal

You may not have compiled the frontend code when updating - this may be skipped depending on your setup.

Run the following command:

invoke update --frontend

And then restart the server. LMK if you see the frontend code then

[Keybored02]

Hi, thanks for the fast response.

Unfortunately it didn't work. invoke update does run without errors, but the issue remains the same.

I also tried stopping the service inventree before invoking, still no luck.

Maybe a general update would benefit it?

I used the provided installer for the initial setup btw.

[SchrodingersGat]

Does the web browser provide any error / warning information in the console?

[Keybored02]

No, there's only a generic warning regarding COOP headers being ignored due to the fact that I don't use HTTPS. This message is common to both CUI and PUI, and it doesn't seem to have any impact.

[SchrodingersGat]

This line in your logs might be important:

13:32:35 server inventree-web-1.service[2275]: Manifest file not found

@wolflu05 @matmair any insights into this one?

[matmair]

@Keybored02 can you please provide the full log from invoke update --frontend ?

[Keybored02]

Sure, full console log here https://pastebin.com/2BP3fWMS

syslog https://pastebin.com/DkP0eSKm

Let me know if you need anything else (and possibly the path to get it, it's all a bit dispersed)

[SchrodingersGat]

If the console log is a complete trace of the command requested by @matmair then this shows a problem - the install command has failed part way through:

This means that the process has not continued - and copied across the required static files to render the frontend. Additionally there are other crucial steps that would have been bypassed also

[Keybored02]

You're right that might be the issue. I'm not sure whether bypassing or manually uninstalling it would be an option?

[matmair]

@Keybored02 please try running sudo inventree run cli update --uv and paste the output again

[Keybored02]

Here it is https://pastebin.com/tsaM6k8s (issue still persists)

[matmair]

Are you running a development version?

[Keybored02]

Yes, [0.17.0 dev]. The default from the installation script.

[matmair]

The installer script defaults to the stable channel. Dev builds do not come with a frontend so this is to be expected.

[Keybored02]

Sorry, isn't the production installer script separated from the developer setup? I didn't use the latter ofc: https://docs.inventree.org/en/latest/start/installer/

I'll try to replicate it on a clean machine.

[Keybored02]

Started am install on a fresh VM and it did in fact default to stable and version 0.16.8. No idea what went wrong here, as i used the same steps as before. Any suggested way to rollback? I definitely can do a backup and reinstall, but would it be backwards compatible?

EDIT I mindlessly started the dev server with invoke server and kept using that as a production. That was stupid. I have tested a few ways to migrate without much success, so now I can either:

1. Switch the branch of my current install to stable and rollback to 0.16.8, hoping for the best.
2. Wait for 0.17.0 to come around in stable and update dev to that.
3. Migrate to a fresh install of 0.17.0 with the current backup files.

I can definitely wait for 0.17 so, I'll go with option 2 for now as I've read that it is a contemplated migration path. My question now regards the way to do so. In particular, how do I switch branches in my current dev setup? Can I then migrate following the docs? Also, can something shed a bit of light on the process used in this discussion (import the mysql data before installing inventree - how)?

[matmair]

We do not guarantee backwards migrations so waiting is probably for the best. Just running the installer script should be enough to migrate to stable.

[Keybored02]

Tried a reinstall with the installer script, and I am now on 0.16.8. The PUI frontend still didn't render. The None text has also disappeared. I tried sudo inventree run cli update --uv and I'm happy to report that it is working now! I'll test this a bit and close the issue if everything runs smoothly.

Thanks to everyone involved for the patience and help!

@Keybored02 glad you got it working :)
