generate_source not working with Snowflake

[MikeHermus]

Describe the bug

I want to add a new source (in Snowflake) to my project by using the generate_source macro, but since recently it is resulting in errors which aren't clear. When I try to run the same macro as an operation in the commandline there seems to be a bit more information available on the error.

Steps to reproduce

1. Compile the macro which looks like this to retrieve the source from Snowflake:

{{
    codegen.generate_source(
        schema_name="jarvis",
        database_name="master_data_prod",
        generate_columns=true,
        include_data_types=true,
        include_descriptions=true,
        include_schema=true,
    )
}}

Resulting error:

2. Run the macro via the commandline:
dbt run-operation generate_source --args '{"schema_name":"jarvis", "database_name":"master_data_prod", "generate_columns":true, "include_data_types":true, "include_descriptions":true, "include_schema":true}'

Resulting error(s):
