langsmith-fetch thread returns Failed to POST /runs/query

[joshb1050]

When running langsmith-fetch thread with a thread ID (that we know exists), we get:

 Warning: Failed to fetch metadata for thread
     <uuid>: Failed to POST /runs/query in
     LangSmith API. HTTPError('400 Client Error: Bad Request for url:
     https://<our internal URL>/api/v1/runs/query',
     '{"detail":"Attribute extra.metadata.thread_id not accepted."}')

This is Version 0.13.14 of Langsmith (self-hosted) and v0.31 of the CLI.

Addressed in #39 if anyone looks...
