file.move return type (MoveResponse) is mostly un-typed

[mgabeler-lee-6rs]

Environment details

• OS: n/a
• Node.js version: n/a
• npm version: n/a
• @google-cloud/storage version: 7.6.0

Steps to reproduce

1. Install the library
2. Observe the Promise-ified return type of file.move

The MoveResponse type (defined at https://github.com/googleapis/nodejs-storage/blob/v7.6.0/src/file.ts#L266) is just [unknown]. This doesn't seem correct, and is certainly unhelpful.

From the definition of MoveCallback (at https://github.com/googleapis/nodejs-storage/blob/v7.6.0/src/file.ts#L268-L274), it seems like it should be something like [File, unknown] matching destinationFile, apiResponse for the non-error version of the callback args.

Thanks for opening an issue @mgabeler-lee-6rs. We are in the process of cleaning up / more strongly typing things within the library. Looking back at the history MoveResponse was originally [Metadata] where Metadata = any. There are quiet a few places where the callback versions don't necessarily align with the promisified version. We intend to clean those up as well. Unfortunately, more strongly typing things / changing signatures are a breaking change that will have to wait until the next major revision of the library.
