Google Cloud Sql Proxy error while executing the file

Question

This is the command I run in my shell: ./cloud_sql_proxy -instaces=[my_project_id:europe-west3:my_project_name]=tcp=5432.

Sometimes i got the following errors messages:

• CASE 1: flag provided but not defined: -instaces;

• CASE 2: 2021/11/19 17:50:12 errors parsing config:

   mkdir my_project_id:europe-west3:my_project_name: The syntax of the file, directory, or volume name is incorrect.
   mkdir my_project_id:europe-west3:my_project_name-copy: The syntax of the file, directory, or volume name is incorrect.
  

Answer 1

Solved by running ./cloud_sql_proxy -instances=my_project_id:europe-west3:my_project_name=tcp:5432 in my shell.
