Hi there!
I wonder if there is workaround for the below behavior.
I'm trying to add a column (an attribute one) to the existing Flow, and  got the below error:
```Failed to generate query for flow=1082 err=0: Datafusion error: Plan("Expect the last column in table to be timestamp column, found column ip_address with type String(StringType { size_type: Utf8 })")```

I assume, this is an expected behavior, that it's not possible to add a tag column to a Flow sink table after it was created. Isn't it worth to mention in the docs somewhere? If it's not an expected behavior, I'm happy to provide more details (a github issue ?), step to reproduce etc

Sorry for the late reply. I’m on a vacation last week. You can drop and create the flow again after you alter the sink table.

<@U04B480RQAH> Please correct me if it isn’t a workaround.

<@U04BHEZQG57> no worries! Thanks for reply!
I'm dropping &amp; creating both table and flow now. Let me try to recreate the flow only.
