AttributeError: '_TelemetryClientHolder' object has no attribute 'close' #52
Description
After creating engine with "enable_telemetry": False using:
engine = create_engine(
f"databricks://token:{self.token}@{self.host}?http_path={self.http_path}",
connect_args={"enable_telemetry": False},
pool_pre_ping=True, echo_pool=True, pool_recycle=1800 # Recycle connections after 30min
)
I get this error at: "/databricks/sql/telemetry/telemetry_client.py", line 546, in _handle_unhandled_exception: client.close()
AttributeError: '_TelemetryClientHolder' object has no attribute 'close'
Since I have "enable_telemetry": False why is this code getting executed at all? Thx

Hello @Bidek56 , apologies for the issue. Which sql-connector version are you using?
This was fixed in
databricks_sql_connectorv4.2.4. Link.Let me know if you face any issues post upgrade too.

@samikshya-db I am using databricks-sqlalchemy as described in the docs
Is there a reason this repo has not been updated to match databricks-sql-connector? Thx

May I know which version of databricks-alchemy are you using?

The latest v2.0.8

Your versions must be locked to a previous version of databricks-sql-connector. Can you upgrade it to use the latest connector version(4.2.4)

I only lock:
databricks-sqlalchemy==2.0.8Then:
pip install -r requirements.txtdoes not updatedatabricks-sql-connectorto the latest b/c this is satisfied:databricks_sql_connector = { version = ">=4.0.0"}frompyproject.tomlLet me find a way to fetch the latest. Thx
