Currently the only way to see the logging output is to launch from the console using
ayon_console addon applications launch --app <app full name> --project <project name> --folder <folder path> --task <task name>so there is no logging by default even when launching using the --debug flag.
I did search the documentation, and looking in the usual locations for log files (%LOCALAPPDATA%\\Ynput\\AYON, etc)but could not find anything about logging from the client.
In conclusion, unless there’s a reason not to, have the client log its output to a file by default?
