in 3.10.0 we have one more header:

>> Accept: application/problem+json

for RFC 9457

[slawekjaranowski]

drop header

>> Accept: application/problem+json

by change in ApacheRFC9457Reporter

    public void prepareRequest(HttpRequest request) {
        //        request.addHeader(HttpConstants.ACCEPT, CONTENT_TYPE_PROBLEM_DETAILS_JSON);
    }

allow to deploy

for standard repository 404 is returned also with Accept: application/problem+json
so I assume that is problem in staging service

[slawekjaranowski]

reference:

• Send "Accept" request header to indicate RFC 9457 compliance maven-resolver#1846 only in 2.x

[slawekjaranowski]

Try to fix in resolver:

• fix: Configuration to be able to control sending RFC 9457 related Accept HTTP header maven-resolver#1891

🎉 testing with:

Accept: application/problem+json, */*

looks ok 😄
