Hi @Aliaksandr-Kasko-JazzTeam thank you for opening an issue. Can you provide us with a bit more information, how often are you seeing this error? Was the code you provided previously working in a different version of the library? Do other operations (i.e. upload) work correctly?

[Aliaksandr-K-JazzTeam]

Hi, @ddelgrosso1.

1. I see this error every time with this mentioned version of library.
2. The code was working with previous versions of library (now I tried with 6.5.0).
3. I can't try other operations like upload because our project is very complex (first we download a file, then we make computations, at last we upload another computed file).

@Aliaksandr-Kasko-JazzTeam by chance have you tried the above on a platform other than Windows, if so what was the result? Is there anything special or different about destination argument? Could you provide a more detailed stack trace? Have you also recently changed versions of Node, if so from what version to 16.13.2.

I tried this in both a Linux and Mac environment with v6.5.2 and was unable to recreate the error you are seeing.

I also tested this in a Windows 10 environment but did not see the issue. @Aliaksandr-Kasko-JazzTeam if you can provide the information from my previous comment I will investigate further.

Don't know if it helps, but getting the same problem on macOS Monterey version 12.6, node version 14.17.6, @google-cloud/storage version 6.5.4. Fixed by switching on node version 16.18.0 (LTS)

Thanks @amerej we believe we have found the cause of this issue and we will be releasing a fix shortly.

[Aliaksandr-K-JazzTeam]

@ddelgrosso1 sorry for my long response and big thanks for fix. Now it works for me
