go-bank's Issues

Error Inserting User into the DB

Bug : Unable to insert user details

• Unable to insert last_name in the Users Table during account creation, even though Insert function is working fine and APi is parsing the JSON request

Possible solution:

• Maybe that's the Postgress container version error, need to update it
• Debug the API parsing request
• Debug the SQL Query
