User TechGeek is experiencing issues with a multisite configuration rebuild, resulting in a background worker "logical replication launcher" (PID 51) exited with exit code 1 error. itsbhanusharma points out that the error message seems normal for the data container, but the web container rebuild is still throwing an error.
After troubleshooting, TechGeek finds that the error is related to a Psych::SyntaxError caused by a formatting error in the app.yml file, specifically in the multisite part. However, validating the file against a YML validator shows no errors.
pfaffman suggests removing the discourse-calendar plugin, but TechGeek is not using it. itsbhanusharma recommends exporting a full log using ./discourse-doctor and checking for a line that says 1 Migration Failed to identify the site causing the issue.

Removing old container
The only plugin I see with sych::SyntaxError is discourse-calendar. Can you try removing it? And if that solves your problem then it implies there is a bug with that plugin
Have checked it against YML validator and no error.
Updated error output below

Pups::ExecError: cd /var/www/discourse && sudo -E -u discourse bundle exec rake multisite:migrate failed with return #<Process::Status: pid 983 exit 1>

exec failed with the params "cd /var/www/discourse && sudo -E -u discourse bundle exec rake multisite:migrate"
bootstrap failed with exit code 1
** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.
During the build there will be a line that says 1 Migration Failed and below it is the info on which site is failing. You need to figure out what is wrong with that site for the build to actually happen.
