3.4.0 API json response problem

Post by Likkie »

After upgrading to 3.4.0 my NZBHydra stopped being able to queue downloads in SABNZB+.

I'm no expert but it seems to me that Hydra is querying SABNZB as to what categories are available so that I can select the right one when adding an NZB to the queue. The response from SABNZB is bad or non-existent, I don't know how to tell... I see a "JSON" error in Hydra...

If I downgrade SABNZB+ back to 3.3.1 everything works fine again.

I'm not sure what other info to provide.

cheers.

What JSON-error in Hydra?

In SABnzbd, set logging to +Debug (via the wrench symbol)
Let the problem happen. Then upload sabnzbd.log to pastebin.com and post the URL (with spaces around the dots) here in this thread.

Hi Sander.

The error I see in Hydra is:

An error occured :
500: INTERNAL SERVER ERROR

No JSON object could be decoded

I have created a debug log file of the issue happening in SABNZB, it is at pastebin with ID: iP3EKpfm (I'm not allowed to post links :'( )

Cheers,

Likkie

I don't see a problem in the sab logging.

Can you into the Hydra logging?
And: I assume hydra2 ?

More suggestions:
3.3.1: OK
3.4.0: not OK

Can you try the intermediate version, so 3.4.0 beta1 and RC1?

the last development on hydra were in 2018: https://github.com/theotherp/nzbhydra/commits/master ...

How about trying hydra2 to see if it has the same behaviour?

Code: Select all

In the meantime:

"Sending categories request to sabnzbd" is from:

https://github.com/theotherp/nzbhydra/b ... #L270-L272

so this method/parameters:

{"mode": "get_cats", "output": "json"}

That is this method: https://sabnzbd.org/wiki/advanced/api#get_cats

Let's try against 3.4.0


Code: Select all

$ lynx --dump '127.0.0.1:8080/api?mode=get_cats&output=json'
{"categories": ["*", "movies", "tv", "audio", "software"]}
so that looks good to me. Same response with 3.3.1 and 3.4.0

OK, so I tried 3.4.0Beta1 and the problem exists there already... :(

Hydra2 is extremely slow in my Docker environment. I don't understand how people are using it.
Its takes many minutes to start and then many minutes to return from a search if it ever does. It seems really broken.

If I have to stay SAB 3.3.1 for now I will. I dont even understand what is "improved" actually.

Cheers,

Erik
