debug error - Failed to set breakpoints

[francescob]

I start my rails app with

RUBY_DEBUG_OPEN=true RUBY_DEBUG_PORT=52203 bin/rails server

then i start the debugger with this configuration:

{ "label": "Attach to Rails server", "adapter": "rdbg", "request": "attach", "cwd": "$ZED_WORKTREE_ROOT", "env": { "RUBY_DEBUG_PORT": "52203" } }

the terminal where i started the server shows that the debugger is connected but in the zed log i see this error:

2025-07-10T10:41:00+02:00 ERROR [project::debugger::session] failed to set breakpoints for "/home/francesco/projects/work/cdss_monitoring/app/controllers/charts_controller.rb": /home/francesco/projects/work/cdss_monitoring/app/controllers/charts_controller.rb is not available 2025-07-10T10:41:00+02:00 ERROR [project::debugger::session] failed to set breakpoints for "/home/francesco/projects/work/cdss_monitoring/app/controllers/concerns/dea_ps_charts_concern.rb": /home/francesco/projects/work/cdss_monitoring/app/controllers/concerns/dea_ps_charts_concern.rb is not available 2025-07-10T10:53:44+02:00 INFO [dap::transport] Debugger closed the connection 2025-07-10T10:53:44+02:00 ERROR [project] client is closed

Hi! Sorry for the late reply, but can you please check if this issue is still happening? I think it was fixed in Zed some time ago. Thanks!
