Broken Lakehouse SQL Endpoint after updating delta table schema

[Dezcraft]

Spoiler

Was using spark + Fabric Lakehouse. After updating a table to a new schema my SQL endpoint (thus the associated datasets) are not retuning any data

Do you have relationships defined in your SQL Endpoint? You may need to remove them: Re: Lakehouse SQL endpoint tables "Sync Error" aft... - Microsoft Fabric Community

Hello @Dezcraft 
Thanks for using the Fabric community.

I tried to repro th issue and I was not able to do that . I did had an existing table , i did altered the schema .

%%sql
ALTER TABLE HimanshuLakeHouse.Address Add  COLUMN new_col_add int

Now when I check the SQL EP , i do see the updated schema . 

What is that I am missing in my repro ?

Thanks
