I updated my angular to v9 and when I try to go back in v8, I receive this error. I have already tried the following:

• uninstall -global angular/cli
• uninstall angular/cli
• go back to my last package.json
• delete node_module folder
• delete repo

This error continues to show.

My stacktrace is :

An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.
See angular-errors.log for further details.

angular-errors.log :
