Describe the bug

Hi, I have copy pasted the streaming code from https://docs.aws.amazon.com/transcribe/latest/dg/getting-started-sdk.html And when executing the code, I've got the following error:

An error was encountered in a non-retryable streaming request.
node:internal/http2/util:633
        throw new ERR_HTTP2_HEADER_SINGLE_VALUE(key);
              ^

I have encountered the same issue yesterday. For my use case, I commented out the following line (in dist-cjs/index.js) and my request starts working:

https://github.com/aws/aws-sdk-js-v3/blob/0b87b64a0290d3aaa4dd9753eab8be66c2598c97/clients/client-transcribe-streaming/src/protocols/Aws_restJson1.ts#L147

Hopefully this workaround can help.

Another clue is that the request headers, I found out it already has: 'Content-Type': 'application/vnd.amazon.eventstream’ which might comes from here: https://github.com/aws/aws-sdk-js-v3/blob/0b87b64a0290d3aaa4dd9753eab8be66c2598c97/packages/middleware-eventstream/src/eventStreamHeaderMiddleware.ts#L8 But I do not know how to fix this yet.

Hi @haochunchang -- thanks sooo much for this. Your workaround is working for me. However, I would still prefer to get this fixed as this is in node_modules and ideally we won't need to change code in the library itself. Let's keep this one open and make sure it catches AWS folks' eyes.

Again, thanks heaps!!

HI @MirandaDora - thanks for reaching out and apology for the inconvenience.

I was able to reproduce the reported behavior and also confirm the workaround mentioned by @haochunchang . I'll bring it up to the team to further discuss and investigate the issue.
