FastAPI-Mail TEMPLATE_FOLDER does not exist - html-email

Question

I was following this example for sending an email using FastAPI HTML templates but it was showing an error related to the templates directory.
conf = ConnectionConfig(
File "pydantic/env_settings.py", line 38, in pydantic.env_settings.BaseSettings.__init__
File "pydantic/main.py", line 341, in pydantic.main.BaseModel.__init__
pydantic.error_wrappers.ValidationError: 1 validation error for ConnectionConfig
TEMPLATE_FOLDER
file or directory at path "/Users/abushoeb/myproject/templates" does not exist (type=value_error.path.not_exists; path=/Users/abushoeb/myproject/templates)

Answer 1

The solution is almost identical to the example with minor modification in the TEMPLATE_FOLDER value.
The whole codebase is available at abushoeb/fastapi.
