HPE_INVALID_HEADER_TOKEN on Departments Request

[peterpme]

Hi,

I'm debugging an issue with the following request: https://collectionapi.metmuseum.org/public/collection/v1/departments

Modern versions of Node and tools like Postman use a strict http parser that turns an HPE_INVALID_HEADER_TOKEN. The only way around this is by disabling the parser, but that comes with its own consequences.

Do you have any insight on this? Should I be calling the endpoint differently? Thank you

@spencerk this is indeed a problem:

> fetch("https://collectionapi.metmuseum.org/public/collection/v1/departments").then(res=>console.log(res))
Promise {
  <pending>,
  [Symbol(async_id_symbol)]: 229,
  [Symbol(trigger_async_id_symbol)]: 195
