Expected behavior

When attempting a data type change for such a column, the operation should either complete successfully, or a clear notification should be provided, indicating that the data type change cannot be executed.

Status

As noted by @Anish9901, further work on this issues is blocked until we re-implement the previews logic with our RPC API.

Found a similar error [Video], is this behaviour expected or we want to show a clear warning message here for the user to understand?

@hitenvidhani I agree it would be nice to improve the error message show in your attached video. Please open a separate ticket to track that though. It's a different issue than the one described here, and I don't want to add confusion to this thread. In general, please err on the side of opening new tickets for things like this, or ask in Matrix in cases where you're not sure if something warrants a ticket.
