Hi, last night we ran into an issue where our Snowflake Connector block had the credential field set to “None” which cause the following errors on our flows

....
 File "/home/ubuntu/.local/lib/python3.8/site-packages/prefect/blocks/core.py", line 175, in __init__
    super().__init__(*args, **kwargs)
  File "pydantic/main.py", line 342, in pydantic.main.BaseModel.__init__
pydantic.error_wrappers.ValidationError: 1 validation error for SnowflakeConnector
credentials
  field required (type=value_error.missing)

This was resolved by switching the credential field back to the correct block instead of the “None” value. Additionally our Slack Webhook URL was “unset/blanked”, leading to alerts not firing off. Is this a known issue? Trying to understand what would cause these fields to be nulled overnight.

Hey @Sean Malone To my knowledge we weren't experiencing any issues that could have caused this last night,For what it's worth I have several flows using the snowflake connector block that seem to be ok, It's definitely odd behavior though if you're able to reproduce the behavior and come up with a Minimum Reproducible example this might be worth opening a bug on our repo for.

Okay ty for the response, I will be keeping an eye on it!
