@dracarys18 @SanchithHegde How do I fix this?

You are returning Report<StorageError> from transaction_async which does not implement From<DieselError>. You should return DatabaseError which implements From<DieselError>

[Azanul]

You should return DatabaseError which implements From<DieselError>

How?

[dracarys18]

You should return DatabaseError which implements From<DieselError>

How?

into_report() converts error to Report instead of that you can use .map_err(err| err.current_context())

I'm looking forward to contributing to hyperswitch even after Hacktoberfest.

Regarding the current PR, I don't think I understand the codebase enough or I'm not that good with Rust yet to see this through. Although I keep trying to do so.
