Persistent Internal Server Error after fresh Digital Ocean droplet deployment v 0.16.8

[levins-law]

Important

This was resolved thanks to feedback herein. These were the steps I took to fix it for me.

1. Ran the inventree command on SSH terminal
2. Looked at the Usage list and noticed there's one called inventree config:set VAR=VALUE
3. Ran the command inventree config:set INVENTREE_SITE_URL=http://162.243.234.188 (replace the URL with your own URL, unclear if this actually fixed the problem, or if the other steps below were the blockers)
4. Still unable to access the web login
5. Went to the very last line of [Breaking] Samesite Cookie Fix #8269 opening post and saw

Users in this predicament should change the value of INVENTREE_COOKIE_SAMESITE from None to False to disable the checks.

6. Went back to SSH console and tried command inventree config:set INVENTREE_COOKIE_SAMESITE=False
7. Ran command inventree restart
8. Still unable to access the website
9. Ran command inventree run invoke update (I may have dealt with the missing invoke package earlier but you may get a prompt to just do that if you haven't already- and thanks to StormTrooper for the extra step.
10. Ran command inventree restart
11. Powered down the DO droplet, then on again.
12. Was able to access the web login page 👍

Deployment Method

• Installer
• Docker Development
• Docker Production
• Bare metal Development
• Bare metal Production
• Digital Ocean image
• Other (please provide a link Steps to Reproduce

Describe the problem*

I have tried several iterations of deploying a fresh DO droplet. Each time I am now prompted with the following error when I try to access Inventree:

Steps to Reproduce

1. Click on the Deploy to Digital Icon logo.
2. Click on the Create Inventree Droplet icon.
3. Create a Basic type droplet, CPU type Regular
4. Create Droplet
5. Go to project, click on Get Started

6. Click on Quick Access to Inventree
   

7. The usual login prompt is missing, goes straight to server error page

You need to specify the INVENTREE_SITE_URL setting, as per the docs:

• https://docs.inventree.org/en/stable/start/config/?h=inventree_site_url#basic-options
• https://docs.inventree.org/en/stable/start/config/#server-access

[levins-law]

@SchrodingersGat thank you for looking at this. This was not necessary the first time I deployed the droplet months ago. I am further confused because the URL and credentials are already provided in the message of the day when I open the SSH terminal.

Please understand that I have no experience with Linux and I can barely manage interacting with the console. I do my best to follow instructions and steps others have shared, but I don't really know what I am doing. Maybe Inventree just isn't for me.

I tried executing root@inventree0168onubuntu2004-s-1vcpu-1gb-nyc2-01:~# inventree config:set INVENTREE_SITE_URL=http://162.243.234.188 but I am still getting the internal server error.

Thanks again for your assistance.

[SchrodingersGat]

This was not necessary the first time I deployed the droplet months ago.

As you can see in our 0.17.0 release notes under "breaking changes" (and also on the release blog) there is a change to the underlying django code which requires an adjustment to your setup.

Read the "Samesite Cookie Fix" section - and this PR for further information

[StormTrooper]

Had the same issue after upgrading a test server to 0.17.0.

Had to change the session cookie as per the above comment and reboot and then also had to rerun the update
inventree run invoke update

[levins-law]

Thank you @StormTrooper, your steps enabled me to access the web login and use Inventree.

@SchrodingersGat thank you as well for your direction. May I constructively suggest that the actual steps needed could be more prominently highlighted in the documentation? I realize you are all volunteers and fielding this many support questions requires concise responses. We are lucky to have you investing in a passion project. For the sake of growing the community to users who are not devs or database experts consider that this experience was not the most welcoming for me.

I will post the steps to resolve explicitly in the initial post for the benefit of other future idiots (which will be me again I'm sure).

Thanks again for everything.

[SchrodingersGat]

@levins-law absolutely. I can add it to the FAQ section, as this is a problem which seems to be impacting a few people. Anywhere in the install docs in particular that you think it should go?

[levins-law]

@SchrodingersGat if you want the perspective of a Digital Ocean user who is able to access the SSH terminal (which I was even thought I hit roadblocks after the build) then I would say you want it where mjmair's MoD appears on login.

A snippet from the message of the day:

On the server:

• This install follows InvenTree's install guide - https://inventree.readthedocs.io/en/latest/start/installer/
• The passwords are saved in /root/.digitalocean_password

If one follows that link they end up here on the Bare Metal section of the install guide.

I think a section right near the Permission Denied Error heading would be appropriate in an [!IMPORTANT] box would help catch the attention of a droplet user.

IDK if this is solely a release-dependent thing that will become irrelevant on your next release, but it's a required setup step going forward I would think it's not release-dependent and needs to be listed as a required step.

More importantly, droplet users will tend to be lower skill (like me). I get the sense there's no impetus to document the DO droplet deployment by itself, but I would challenge that assumption. Perhaps on the website front end (screenshot below) it would be worth mentioning there are like three extra commands you will need to know.

I got into this predicament because I followed the documentation about updating Inventree which broke the hell out of my instance. To quote mjmair

please do not upgrade to a version that I have not supported

The documentation linked in the MoD is the installer heading, which is full of all sorts of things that perhaps one should not do. This is worth mentioning.

I really appreciate the call for feedback and hope it helps others.

[SchrodingersGat]

I have made some updates to the install / setup docs here: #8777
