[Bug]: Embed pictrs doesn't work

[arne-fuchs]

Requirements

• Is this a bug report? For questions or discussions use https://lemmy.ml/c/lemmy_support
• Did you check to see if this issue already exists?
• Is this only a single bug? Do not put multiple bugs in one issue.
• Is this a backend issue? Use the lemmy-ui repo for UI / frontend issues.

Summary

I followed these steps to install the lemmy server from scratch by using the steps below.

But after trying to upload a picture it says that it cant parse json on line 1.
If I start up a pictrs server and then try to upload a picture, lemmy server starts to talk to the pictrs instance running locally.

So the --features embed-pictrs flag has no effect.

Building without the flag has the same results.

Steps to Reproduce

1. git clone https://github.com/LemmyNet/lemmy.git lemmy
2. cd lemmy
3. git checkout 0.18.0
4. git submodule init
5. git submodule update --recursive --remote
6. cargo build --release --features embed-pictrs
7. Try to upload picture

These logs are being printed when upload a image:

The reference to http://localhost:8080/image in the logs looks to me like the pictrs url isn't set up properly in the lemmy.hjson.

@dawtmaytrikx Thanks for your response. I have a different setup than the guy in the post. He is using docker and I've build form scratch. At his scenario he is using an own pictrs instance while I have build from scratch, where I add prictrs as compile feature.
If I look in my netstat, there is no pictrs instance listening for request either. But I do not know how it is implemented.

I get following error from lemmy when starting it:

Jun 26 20:36:57 ns3030678 lemmy_server[2259490]: thread 'main' panicked at 'run pictrs: IO error: Not a directory (os error 20)

[arne-fuchs]

Fixed it by setting

WorkingDirectory=/path/to/your/liking

in my service file and creating a pictrs folder and change the ownership to lemmy.
Should be included in the documentary.

I also got this error the other day when trying to upload an image that was too large. Just for others that might find this issue thread.
