Relevant telegraf.conf

Not sure which config triggers this.

This seems to be snowflakedb/gosnowflake#1533.

[IngmarStein]

I encountered this in a Homebrew installation which doesn't set HOME. If I manually patch the launchd plist to set this environment variable, Telegraf starts successfully.

[mstrandboge]

Yes it appears that this is caused by the above issue in the snowflake library. It looks like there are some listed workarounds in the issue, with the HOME and SNOWFLAKE_CRL_ON_DISK_CACHE_DIR environment variables. We will likely roll back this library update in the next telegraf update if we are unable to update it to a version that includes the patch from snowflakedb/gosnowflake#1526

[IngmarStein]

@mstrandboge I've created Homebrew/homebrew-core#236746 to fix this for Homebrew users in the meantime.
