npm error HPE_UNEXPECTED_CONTENT_LENGTH

[RenaudDemarneffe]

Hello,

I deployed Nexus OSS with nexus-proxy on a k8s cluster through the helm chart. I don't use GCP IAM authentication.
I followed the documentation to configure the npm repositories.

When I try to download a package, I got the error HPE_UNEXPECTED_CONTENT_LENGTH.

The full error stack is the following:

The error seems comming from the nexus-proxy because when I disable the nexus-proxy and directly access the nexus I don't get the error.

Is there a configuration parameter to avoid this error?

Thanks for your help.
Reagrds,

Hi , have you tried the suggested solution here:

[RenaudDemarneffe]

Hi, I tested the solution but it doesn't work.

[marianocodes]

I'm experiencing the same problem, @RenaudDemarneffe Did you find a workaround?

[RenaudDemarneffe]

Hi @mahcr, I have updated the order used to set the headers of the response but I don't know if it's the right solution.

Could you fix this issue? Thanks in advance

@TAvardit I have the same problem with PyPI.

I used twine for the upload and it works properly.
But when I try to install the package using the command:
pip install <pkg_name> --extra-index-url <repo_url>

the error appears:
WARNING: Received response with both Content-Length and Transfer-Encoding set. This is expressly forbidden by RFC 7230 sec 3.3.2. Ignoring Content-Length and attempting to process response as Transfer-Encoding: chunked.

Having the same issue here, any update to this?
