No collation was set by the server for the current connection

I’m following BulkLoad docs to insert multiple rows at once in my database. I’m getting this error:

No collation was set by the server for the current connection in TediousJS

When my script tries to execute the following line:

bulkLoad.addRow(TYPES.Null, col2, col3, col4, col5, TYPES.Null, col7, 
                                col8, col9, TYPES.Null, TYPES.Null, TYPES.Null);

What does this error mean? Why I haven’t gotten it before using bulkLoad? How do I solve this?

Thanks!

Thanks for being so helpful in getting down to the root cause of this issue! I’ll make sure that we really highlight this better in our documentation that the connection is in a half-baked state if you don’t wait for the .connect callback to fire. 🙇‍♂️

Okay. 😅 That at least makes sense now! I’m going to try and reproduce this (I have a Azure SQL instance with the same collation settings). I’ll let you know if I can find something!
