Updating @opentelemetry/exporter-trace-otlp-http to 0.44 breaking exports

[TomPeas]

So I have been using "@opentelemetry/exporter-trace-otlp-http": "0.35" for a while now to export my traces to new relic. It has worked mostly fine. I then tried updating to 0.44.0 along with updating all other otel packages to the lastest version. All worked fine other than this exporter. When I update to 0.44.0 the traces just don't seem to export to new relic at all, I have changed nothing in my config or setup for the trace exporter. I have keep the older version I get traces, I update I don't and there isn't anything obvious in the debug logs.

const provider = new NodeTracerProvider({
  resource,
  sampler: new AlwaysOnSampler(),
});

const exporterConfig = {
  url: 'https://otlp.nr-data.net:4318/v1/traces',
  headers: { 'api-key': process.env.NEW_RELIC_LICENSE_KEY },
  concurrencyLimit: 10,
};

const traceExporter = new OTLPTraceExporter(exporterConfig);

provider.addSpanProcessor(
  new BatchSpanProcessor(traceExporter, {
    maxQueueSize: 1000,
    scheduledDelayMillis: 1000,
    maxExportBatchSize: 1000,
  })
);
