Missing snowflake URL in demo

[EdwardYGLi]

My company (Socure) is currently doing a POC with tecton and when trying this tutorial. I get the below errors:

Traceback (most recent call last):
  File "/local_disk0/pythonVirtualEnvDirs/virtualEnv-1f7c4e9d-d90a-428a-bbc0-2fdf6babe447/lib/python3.8/site-packages/tecton_materialization/remote_host/pyspark_remote_host.py", line 289, in execute

    assert request.HasField("url"), "url cannot be None"

and

I cannot find any credentials or URLs for snowflake that I can connect to to try out the demo, please let me know how to proceed.

Thanks.
