@opentelemetry/otlp-transformer throw error when run in old Android webview, throw error "Cannot redefine property: name"

[fengyangbj-kanyun]

What happened?

@opentelemetry/otlp-transformer:0.52.1

When running the code that imports the current package in a low version webview（for example: Android 5.1.1; vivo X7L Build/LMY47V) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/39.0.0.0）, the error message is as follows:

Uncaught TypeError: Cannot redefine property: name

I traced the code, found the code in node_modules/@opentelemetry/otlp-transformer/build/src/generated/root.js

Object.defineProperty(TraceService.prototype["export"] = function export_(request, callback) { return this.rpcCall(export_, $root.opentelemetry.proto.collector.trace.v1.ExportTraceServiceRequest, $root.opentelemetry.proto.collector.trace.v1.ExportTraceServiceResponse, request, callback); }, "name", { value: "Export" });

Object.defineProperty(MetricsService.prototype["export"] = function export_(request, callback) { return this.rpcCall(export_, $root.opentelemetry.proto.collector.metrics.v1.ExportMetricsServiceRequest, $root.opentelemetry.proto.collector.metrics.v1.ExportMetricsServiceResponse, request, callback); }, "name", { value: "Export" });

Object.defineProperty(LogsService.prototype["export"] = function export_(request, callback) { return this.rpcCall(export_, $root.opentelemetry.proto.collector.logs.v1.ExportLogsServiceRequest, $root.opentelemetry.proto.collector.logs.v1.ExportLogsServiceResponse, request, callback); }, "name", { value: "Export" });

When executing the above 3 code segments, Android low-version webview will report an error "Cannot redefine property: name" because these webviews will throw an error when the name attribute of the function is modified.

I don't know what the three lines of code do, and the code runs normally without any errors when I comment out those lines. Hi, friends, if I want to fix this problem, what should I do? Thank you very much.

The error happens in code that is generated by the protobuf dependency required to serialize output. Unfortunately I don't know if we will be able to support such an old version of android webview as we don't have control over the protobuf code generation. Which exporter are you using?

I'm going to remove the bug label since this is an old unsupported version of android. I'll leave the issue open for now so we can hopefully find a workaround for you.

Thank you for your reply and look forward to a workaround, thank you very much！
