Is there any possibility there is a problem with the 429 response? So something is converting to say a bad gateway error because it doesn’t like the 429?

Not trying to criticize if this was already checked. Just something I’d try to double check out of being overly cautious.

Expires header in the past seems suspect. And all the header names are lowercased.

It's usually used to prevent caching from older caching systems.

Fun fact: this specific value of Expires is the birthday of Sasha Schumann, the person who added this code to PHP[1][2].

Expires header in the past is typically used to prevent caching.

The lower-case headers is part of the http2 specification.

[niloc132]

Lower case headers are required for http/2 requests and responses.
