Search Error in KOReader

[cebo29]

Since a Short Time I get a 400 Bad Requests, if i search for a book in ODPS feed. If go thru the Categories i will find the book und can Download it.
If i search in Browser there ist no problem.

COPS itself does not reply with 400 Bad Request, so something else must have changed either on the server/container/NAS it's running on, or with KOReader.

Can you provide any more details, like any version or configuration changes and/or server logs?

I use the linuxserver.io Docker Image and start it with a docker comopose file.

services:
cops:
image: lscr.io/linuxserver/cops:latest
container_name: cops
healthcheck:
test: wget --no-verbose --tries=1 --spider http://localhost/ || exit 1
interval: 60s
timeout: 10s
start_period: 5s
retries: 4
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/Berlin
volumes:
- ./config:/config
- /mnt/Multimedia/calibre:/books
ports:
- 81:80
restart: unless-stopped

In the Docker Log i didn't find anything.

Hi @cebo29 thanks for that.

In your local ./config directory you should have access to both nginx/access.log and nginx/error.log, and php/error.log.

It may be that the error.log files don't contain anything - I believe you need to change the error_log to "info" for nginx to report why it sent back 400 Bad Request.

But could you find out in the nginx/access.log which URL KOReader was trying to reach when it got the 400 error, and how it compares to previous/next URLs?

172.19.0.1 - - [19/Nov/2024:17:19:50 +0000] "GET /index.php/feed HTTP/1.1" 200 4327 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36"
172.19.0.1 - - [19/Nov/2024:17:20:04 +0000] "GET /index.php/feed/search HTTP/1.1" 200 503 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36"
172.19.0.1 - - [19/Nov/2024:17:20:14 +0000] "GET /index.php/feed?query=ali HTTP/1.1" 200 1258 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36"

The last line will probably have "GET /... HTTP/1.1" 400 ... instead of 200 then.

Hi @mikespub,

thank you for answer.

My error log from 18.11.:

2024/11/18 17:57:30 [error] 280#280: *17969 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 10.1.1.72, server: _, request: "HEAD /feed.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "10.1.1.220:81"
2024/11/18 17:57:30 [error] 280#280: *17971 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 10.1.1.72, server: _, request: "GET /feed.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "10.1.1.220:81"

I think this is another error!

I have a access log with 400 entries:

Where can i change error log to info?

I recognized that a search without a space give me a result without errors. If i have a space in the search like "maddrax 56" i get the Bad Request Error.

Thanks, that really helps pin down the issue - it seems I still missed a rawurlencode() to deal with spaces in the query param when switching to route URLs. I'll try to fix that for the next release...

Note: that first /feed.php error is from before you switched the URL to /index.php/feed and it (correctly) states that there is no more feed.php script. The old endpoints were indeed removed in release 3.3.1
