Error while fetching tags with either plugin using Docker on Synology

[drummingdemon]

LRR Version and OS
LRR: 0.8.5
OS: Synology DSM 7.1-42661 Update 2
Docker: 20.10.3-1306

(I did try it under macOS 12.4 as well with Docker 20.10.17, build 100c701 - same results)

Bug Details
LANraragi seems to be unable to fetch external metadata, either from nHentai or EH - regardless of batch processing or editing a single Archive Metadata. Importing Tags using the nHentai plugin yields the following error message:

Error while fetching tags :
Error: malformed JSON string, neither tag, array, object, number, string or atom, at character > offset 0 (before "(end of string)") at /usr/local/share/perl5/site_perl/Mojo/JSON.pm line 31.

Sending ping commands from the CLI of the container work towards IPv4 addresses and hostnames as well - first I though hostname resolution is somehow not working, but that doesn't seem to be the case.

Application log

[2022-07-03 12:13:14] [nHentai] [debug] Skipping search and using gallery 388859 from oneshot args
[2022-07-03 12:13:14] [nHentai] [debug] Detected nHentai gallery id is 388859
[2022-07-03 12:13:14] [nHentai] [debug] Tentative JSON: {}

Screenshots

Did anyone else experience something similar? Other Docker containers work fine in both environments, so I'm at a bit of a loss here where to continue.

Did you configure the nHentai CF Bypass values in your Plugin Configuration? Do you get Cloudflare loading pages when visiting either website?

My guess is that it is a problem with ne new alpine baseimage, had the same problem until i built an own image with the old baseimage

[drummingdemon]

Thanks all, it seems that somehow my plugins are outdated and the nHentai CF Bypass plugin is missing from my instance even though i've pulled the :latest image today and created the container from scratch.

Also the nHentai Metadata plugin was one version behind the current at 1.7.1 - so adding them by hand via upload finally fixed it and tags are coming in, when editing an archive manually.

However, for batch operations with a timeout of 5 seconds, I get the following error:

Error while processing ID 81a922237d4cca2e4911ad38a97464f3b0e5b0b4 (Invalid argument at /home/koyomi/lanraragi/script/../lib/LANraragi/Plugin/Metadata/nHentai.pm line 102.
)

Any ideas with that? Much appreciated!

It still sounds like Cloudflare. Do you get an error on the first attempt, or does it work on occasion? Line 102 is within the get_gallery_dom_by_title sub. I'd try changing the plugin to get it to log the variables inside. You can use "$logger->debug();" to output the variables inside it to try and figure out exactly what's being processed.

Invalid Argument errors can also come from the Alpine bug @Pheromir mentioned, so I'd recommend trying to build an image with https://github.com/Difegue/LANraragi/blob/dev/tools/build/docker/Dockerfile-legacy to see if that improves things for you!

Thanks, I had problems with building the legacy Dockerfile and sadly hadn't had the time to look into it since. The error still persists with the current image on the Synology NAS.

Sadly I haven't added the legacy/alpine 3.12 builds to the release pipeline so there are no autobuilds of it 🤔
The latest released image is still on alpine 3.14 so you're indeed still going to have the issue.

I can confirm same kind of errors when using chaika and fakku metadata plugins, same-ish environment of synology with docker. So it isn't a Cloudflare.

Error: Invalid argument at /home/koyomi/lanraragi/script/../lib/LANraragi/Plugin/Metadata/Fakku.pm line 134.

Error: Invalid argument at /home/koyomi/lanraragi/script/../lib/LANraragi/Plugin/Metadata/Chaika.pm line 143.

I rolled back to 0.8.4 so I could setup the metadata for all galleries...

I tried building with the legacy dockerfile but didn't help, not sure why.
