@pavolloffay I'd need your insights because the TestTracesTempo test fails with:

=== NAME  TestTracesTempo/write-then-query-single-trace
    traces_test.go:609: �[31mhelpers.go:127: "failed to assert that the response '{"batches":[{"resource":{"attributes":[{"key":"service.name","value":{"stringValue":"my.service"}}]},"scopeSpans":[{"scope":{"name":"my.library","version":"1.0.0","attributes":[{"key":"my.scope.attribute","value":{"stringValue":"some scope attribute"}}]},"spans":[{"traceId":"W47/95gDgQPSabYzgT/GDA==","spanId":"7uGbfsPBsXQ=","parentSpanId":"7uGbfsPBsXM=","name":"I'm a server span","kind":"SPAN_KIND_SERVER","startTimeUnixNano":"1544712660000000000","endTimeUnixNano":"1544712661000000000","attributes":[{"key":"my.span.attr","value":{"stringValue":"some value"}}],"status":{}}]}]}]}' contains '{"batches":[{"resource":{"attributes":[{"key":"service.name","value":{"stringValue":"my.service"}}]},"scopeSpans":[{"scope":{"name":"my.library","version":"1.0.0"},"spans":[{"traceId":"W47/95gDgQPSabYzgT/GDA==","spanId":"7uGbfsPBsXQ=","parentSpanId":"7uGbfsPBsXM=","name":"I'm a server span","kind":"SPAN_KIND_SERVER","startTimeUnixNano":"1544712660000000000","endTime...(output trimmed)"�[39m

Debugging locally I can see that the difference between the returned and expected traces is around the scope attributes.

The returned trace has:

...
          "scope": {
            "name": "my.library",
            "version": "1.0.0",
            "attributes": [
              {
                "key": "my.scope.attribute",
                "value": {
                  "stringValue": "some scope attribute"
                }
              }
            ]
          },
...

while the test expects no scope attributes
