Postman not decoding gRPC response correctly

While eliciting a gRPC request to Postman, the response is having issues correctly printing out the uint64 keys of my protobuf file shown below:

"component_output": {
                     "5Öd\u0000\u0000\u0000\u0000": 299310.5,
                     " UZ¶\u0000\u0000\u0000\u0000": 7816.4365234375,
                     "a¦±_\u0001\u0000\u0000\u0000": 6820.3505859375, ...}

However, they should be giving the following, which is what’s logged using JsonConvert.SerializeObject, and is correctly parsed through Console logs.

"ComponentOutput": {
                     "1686885941": 299310.5,
                     "3059373472": 7816.4365,
                     "5900445281": 6820.3506,...}

It would be great if I could fix the Postman response to look like the latter. The current type of component_output field in the gRPC message is map<uint64, float>.
