I was receiving HPE_INVALID_CONSTANT
when making HTTP requests with NodeJS the other day. They mysteriously stopped occurring recently, but I'm still baffled and curious what exactly HPE_INVALID_CONSTANT
is trying to tell me.
My google search results are a bit slanted towards NodeJS, so I'm not picking up anything that describes more generally what this means. It looks like a system level error since it's all caps.
