Error 500 on /studio/add-link

[Ti-Tom]

When adding a link (url = /studio/add-link), the Yaml lib seems to be missing when doing a composer install --no-dev.
The error appeared on the latest version of the docker image.

A composer install solves the problem but install unnecessary libs.

Same issue. After trying the "compose install" the page started working, sort of, but not properly. I have a spinny thing on the page that doesn't finish. As the last changelog references removing a discontinued dependency, it's likely that doing so broke something.

Also having this issue.

Just installed an instance on ProxMox in an lxc via community-scripts, and I get the same 500 error. I tried an apt install composer and rebooted the lxc, but no change for me.

v4.8.5
/studio/add-link

[xanathon]

I installed using SQLite on premium shared hosting and have the same problem.

[xanathon]

I will now downgrade to 4.8.4 to see if that works.

[xanathon]

Confirmed: 4.8.4 works.

[schnippendullerich]

Same error. Sorry for the extra post. Shall I delete it?

[electricsteve]

Yes definitely one of these changes caused it: v4.8.4...v4.8.5

[mpca86]

Hi, i have same problem in shared hosting:

[lastsamurai26]

We are aware of this bug and ask for your patience. At this time, it is only possible to downgrade to 4.8.4.
This can be done manually by placing the update package for version 4.8.4 in the httpdocs folder.

If you use Docker, This is not a Docker bug.
The Docker images only provide the version at the time of build once; all other versions are provided via the internal Linkstack Updater, so downgrading via tags is not possible.

[mbirth]

Looks like symfony/yaml is only required by some development package, but not by the prod packages. Thus no autoload information is generated for it.

This fixed it for me:

composer require "symfony/yaml ^6.0|^7.0" --update-no-dev

[hoonsubin]

also having the same issue. Hope the new version fixes it.

Same problem here -- Can you please illuminate where I can downgrade to 4.8.4? I cannot find a docker pull image for that, the tags don't seem to work...
