Databricks excel plugin error

Hi, i have an error with the excel pluging.

It was working fine until today. I can login and browse the catalog but I get an error when trying to query any data. It seems like its sending in a blank warehouse id. I have choosen a warehouse and its running.

Anyone who knows what the reason can be?

Error message:
Excel operation failed in TableSelector: {"ok":false,"status":400,"statusText":"","json":{"error_code":"INVALID_PARAMETER_VALUE","message":"INVALID_PARAMETER_VALUE: is not a valid endpoint id."},"body":{},"statement":"SELECT `report_concept_id`, `code`, `name_no`, `name_en` FROM `tower-cs_dev_base`.`heartbeat`.`report_concept` LIMIT 1000","warehouseId":""}

It looks like the issue is coming from the Snowflake Excel connector not receiving a valid warehouse/endpoint identifier when executing the query.

Since login and catalog browsing work fine, authentication is OK — the failure happens at query execution time, which usually points to one of these causes:

The selected warehouse session context is not being passed correctly (blank/invalid warehouse ID)
The worksheet/excel plugin session lost the warehouse binding after an update or session timeout
The connector update changed how endpoint/warehouse IDs are resolved (this has happened in recent connector versions)

What you can try:

Re-select the warehouse in the Excel plugin and reconnect (don’t rely on the previously selected one)
Fully log out of the Excel plugin and log back in
Restart Excel to clear cached session metadata
Verify the warehouse is active and not suspended
If multiple accounts/regions are used, ensure you're connected to the correct Snowflake account endpoint

If it started suddenly today, it’s very likely a session/connector-side issue rather than a SQL problem.

If the issue persists, checking the latest Excel connector version or reinstalling it often resolves this type of “invalid endpoint id” error.
