tl;dr: when getting "Your view is erroneous and could not be processed." in docker environment check:

1. system setting has proper hostname setting
2. proxy is sending correct "Host" and "X-Forwarded-Proto" headers (see below)
3. if OP is not running in subdirectory (which should be default in docker) DON'T set OPENPROJECT_RAILS__RELATIVE__URL__ROOT=/
   just omit OPENPROJECT_RAILS__RELATIVE__URL__ROOT at all

If OPENPROJECT_RAILS__RELATIVE__URL__ROOT=/ is set the api requests from your browser won't have a hostname set and thus will fail (look into developer mode of your browser).

Hi,
I have migrated from a package based installation to docker. I am now running the latest OP 10 image. After a few hickups with worker/seeder everything seems to run without errors. But when accessing work packages of existing projects I get following message:

Your view is erroneous and could not be processed.

I have tried to get more informations from the web container:

But I thinks this is not helpful. I have read in another thread that running "openproject configure" maybe helpful. But as this is a docker installation this doesn't apply here, does it? If it does: how to run "openproject configure" in docker?

Any idea what went wrong or where to get more informations from?
