createWriteStream() with resumable true results in absolute URLs error on 1.45.1

[byumark]

We recently upgraded to fake-gcs-server 1.45.1 and started getting the following error from google-cloud/storage when streaming to the fake gcs server using createWriteStream():

TypeError: Only absolute URLs are supported

When we move back to 1.45.0, then we no longer have the issue. Also, if we set resumable to false then 1.45.1 does not cause an error. For example:

createWriteStream({ resumable: false })

Thanks for reporting and apologies for the breakage. This is the same issue as #1166 (different SDKs have different error messages).

I broke it in #1159. #1184 fixes it.
