Databricks excel plugin error

[oyslan]

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.
