can we use App error here

You can't use AppError here, this will be integrated in other codebases that may or may not understand the struct AppError

can we use different param for prefix, since its not related to the context instead with the filter,
we also might need to change this in cac_client

can we expect prefix as array of strings instead of comma separated string(since this is not query params of any api),

Is there a need for this? Will we ever get an error?

Wanted to maintain consistency everywhere. Maybe in future.

Can we not do it then? Lets add it when the error comes

It's already removed, you seeing the code on the opposite(removed) side.

This comment is not removed .
This was the comment that was removed :
// println!("variantIds: {:?}", variants);

Can we make this change at all the places ?
Ideally match statements should be used only for the cases where we have more than 2 conditions to match .
For these cases , we can directly leverage map .
