Hi,
We are unable to reproduce the issue with our java http client. This issue happens when the http request is made from a real device and http client resides in the device.

we tested with the later version of node js binary(10.19.0), but issue still happens with below error

we share the pcap if is required?
can you please help us to understand the issue..

[marco-ippolito]

yes please without a tcp dump it's very impossible

Why is there a NaN chunkSize before the error throws?

HTTP 24389: SERVER socketOnParserExecute 1398
HTTP 24389: SERVER socketOnParserExecute NaN
HTTP 24389: parse error { [Error: Parse Error]
bytesParsed: 909,
code: 'HPE_INVALID_CHUNK_SIZE',

Can you provide a minimum reproducible repo or a gist?
