400 Bad Request on first namespace creation / Error 500 on /api/v1/info

complete newbie here but after doing a fresh install on my server I have 2 issued which I believe are related.
The initial API call to /api/v1/info returns a 500 Internal Server Error and the PUT call to /api/v1/namespaces returns a 400 Bad Request and this error message:
Screenshot 2021-02-22 at 19.27.03

I am running the frontend on todo.domain.com and I am using the nginx reverse proxy setup described in the docs (without GZip).
I have tried using backend versions 0.16, 0.16+17 and 0.15+82 and frontend version 0.9.

Thanks in advance.
Kind Regards

The frontend version 0.9 is very old, please try a more recent one. Compatible frontend and api versions share the same version number, so if you want to use the api in version 0.16, you should use the frontend in version 0.16 with it.
That should solve the “Bad Request” issue.

Do you have anything in the logs about the request to /api/v1/info?

Hi, thanks for the help.
Changing frontend made it worse as now I cant get past the login page.
I turned on verbose logging of everything and I’m not get anything in the logs.
Seems like I messed the install up as the frontend now returns 'Could not find or use Vikunja installation at “todo.domain.com:3456” ’


Is the API reachable from the outside, aka from the browser?

Could you share your configuration?

Can you reach the /API/v1/info endpoint? If that doesn’t work, you won’t be able to change the API URL in the frontend.

The API is reachable from the browser. calling /api/v1 returns {"message":"missing or malformed jwt"} which is to be expected.

calling the /api/v1/info endpoint with a browser or postman with headers returns a 500 Internal Server Error, but as I said no sign of anything in the logs.
I can upload my configs if you like, but they are very close to the default config/ configs shown in the docs.

Thanks for the help

/etc/vikunja/config.yml → service: # This token is used to verify issued JWT tokens. # Default is a - Pastebin.com

/etc/vikunja-front/index.html → <!DOCTYPE html><html lang="en"><head><title>Vikunja</title><meta charset="utf-8" - Pastebin.com

Looks like you’re hitting this: #767 - `500` on `/info` with deafult config - api - Gitea

To fix it, you have two options: Either set openid > providers > name/authurl/clientid/clientsecret to "" in the config or upgrade the frontend and the API to unstable which contains a fix.

Hi, I think there is something even funkier going on.

Neither changing to unstable nor setting the openid provider variables to “” changed anything.
I tried accessing the site with a different device too, but the results are always the same. 500 when calling /info.

I’m at a complete loss haha


Nothing in the logs? Even with debug logging enabled for everything? There should be at least some sign of the logs working, if the log files are completely empty you may want to change that to stdout instead. What exact version are you using? (Run vikunja version and paste the output)

I set the logs to stdout and debug but still nothing useable.

The version is Vikunja api version v0.16.0+83-4880a0265b

But you do see the 500 in the logs? (just to confirm the logs are working)

Hi, sorry for the delay. I re-checked the log config and it’s all set to the most verbose. I tried logging to stdout and to a file but there’s no sign of the 500 anywhere

Then there should be something in the nginx logs. At least some sign of a 500 somewhere.

OK i found this in the nginx logs:

Hmm that looks like nginx got an error from the proxy upstream which is Vikunja in this case. So the error does occur somewhere in Vikunja and not in the proxy.

Could you provide all config and its setup so I can recreate and hopefully reproduce it? It definitely looks like a weird bug.

Oh and I guess you’ve already checked the basic things like the server itself is working properly etc?

I was debugging this in the Cloudron package. A call to /api/v1/info seems to result in some sort of crash (not a Go expert). Let me know if I can provide you with any more information. Note that the app itself works fine, frontend is fine etc. It’s only when I do curl https://vikunja.cloudron.com/api/v1/info, I get this backtrace.

I am using Vikunja 0.16.0

Ah so, I was wrong about this back trace appearing only for /api/v1/info. When I register a new user, I get the same trace again. But it doesn’t seem to stop the backend/frontend from working. I can register a user, login, creates namespaces/lists/tasks etc just fine.

Yeah that’s 400 Bad Request on first namespace creation / Error 500 on /api/v1/info - #7 by kolaente

(In hindsight I really should’ve published a fix release…)

Sorry, I thought it was already in the latest release! I guess we will wait for the next release then, thanks.

Unstable has the fix but is, well, unstable.
