'If-None-Match' and 'If-Modified-Since' Headers being Appended to Outgoing Network DELETE Requests Resulting in Server 501 Error

[ChristopherGabba]

Description

I send a DELETE request using the AWS Amplify S3 remove({ key }) function and two headers:
If-None-Match and If-Modified-Since are being added to the DELETE request resulting in a 501 Server Error.

{
    "title": "NotImplemented",
    "message": "A header you provided implies functionality that is not implemented",
}

I could not catch them with any Debugger (Reactotron, Chrome Debugger, etc.) but finally caught them using Charles Proxy:

Failed Network Request

Successful Network Request

Steps to reproduce

I tried for weeks to make a reproducible example but failed, so I will provide private repo access to whomever is assigned the issue and provide a simulator build (.app file) and exact steps to reproduce easily.

It is occurring 50% of the time in my mobile app and is very easy to reproduce. Just let me know who is assigned the issue and I will grant repo access
