Resolution

• Connect to the server via SSH.
• Reinstall extension(s) mentioned in the error:
  
  Code Select Expand
  #plesk bin extension --install <extension name>
  where <extension name> is the name of the extension mentioned after /usr/local/psa/admin/plib/modules/
  in the error message. Use lowercase letters only in the command.
  
  For example: if /usr/local/psa/admin/plib/modules/nodejs/... is mentioned in the error, then use the
  command:
