OPA Bundle | bundle service does not receive 'If-None-Match' header from OPA service

[GalHalupSeaLights]

I implemented my own bundle API service which response with a bundle.tar.gz file and Etag header.
On every call to get the bundle I see these logs in my OPA service.
Even though I can see the the OPA service is receiving the Etag header and updates the Etag value in the service I do not receive the If-None-Match header on each GET request to download the bundle.
I'm also attaching my Bundle API service log that prints all headers recieved on each API call.

Hi @GalHalupSeaLights! If the user-agent header is correct, you are testing this using OPA v0.24.0? That version is... old.
Let's start by having that updated to the latest OPA version and then take a look at what the request looks like today. I don't know what changed since then, if anything, but at least we'll be at a good starting point for this discussion 🙂
