After upgrading: type error when POSTing body using a generated TS client

[IkeOTL]

I upgraded from

"@microsoft/kiota-abstractions": "^1.0.0-preview.57",
"@microsoft/kiota-http-fetchlibrary": "^1.0.0-preview.56",
"@microsoft/kiota-serialization-form": "^1.0.0-preview.46",
"@microsoft/kiota-serialization-json": "^1.0.0-preview.57",
"@microsoft/kiota-serialization-multipart": "^1.0.0-preview.35",
"@microsoft/kiota-serialization-text": "^1.0.0-preview.54",

to
"@microsoft/kiota-bundle": "^1.0.0-preview.72"

And now I get this error when calling a POST function on a TS client generated using dotnet tool microsoft.openapi.kiota = 1.19.1
error:

It seems that kiota's serializer is providing a Arraybuffer while the validChunk is expecting a string or Buffer. Maybe something is wrong with the compression middleware? Unfortunately I cannot figure out how to disable the compression middleware

Thanks for raising this @IkeOTL

Unfortunately I cannot figure out how to disable the compression middleware

At the moment, I believe you can use this example to create a httpclient and then pass it to the request adapter constructor.

kiota-typescript/packages/http/fetch/src/kiotaClientFactory.ts

Line 38 in fcef711

* KiotaClientFactory.create(undefined, [middleware1, middleware2]);

@rkodev Any chance this is related to compression handler issues at #1442 as well?

Hi @IkeOTL, it looks like the issue was with zlib compression that has been dropped with version 77. Kindly update your dependecies to version 77 and share if you still have the problem

@rkodev I've updated to "@microsoft/kiota-bundle": "^1.0.0-preview.77" but now my PUT request is producing garbage. I'm assuming its compression?

[rkodev]

Yes, this is as a result of compression. You can disable compression if you would like to see the payload

    const http = KiotaClientFactory.create(undefined, [
      new RetryHandler(), new RedirectHandler(), new ParametersNameDecodingHandler(), new UserAgentHandler(),  new HeadersInspectionHandler()
    ])
  
    const adapter = new FetchRequestAdapter(new BearerAuthenticationProvider(), undefined, undefined, http);
    const client = createApiClient(adapter);

    client.api.endpoint.post({
      field: "testdata",
    })
