Certificate error

Start with the Docker startup path shown in the stack trace, especially packages/backend/dist/main.js, gitlab.js, and utils.js, and trace the @gitbeaker/rest request. Reproduce the self-hosted GitLab certificate failure, then define and verify the supported certificate injection or bypass behavior for the container.

Hi, I'm trying to use sourcebot for indexing a self-hosted instance.
When I start the docker image it immediately stop with this error:

while debug is active, it's not very clear to me which certificate it's complaining about (I suppose it doesn't like my gitlab instance has a self-signed certificate, also I am behind a proxy) and how can I inject my certificates or eventually ignore them.

Is there a way to do it?

Thanks
