Error in parsing response body

[kobofare]

Use jdsom and vitest to write unit tests. sends a grpc request to the envoy proxy. When the number of bytes returned is less than 16k, it can be returned correctly. Otherwise, the error "Error in parsing response body" will be reported.
jsdom:25.0.0
vitest:2.0.5
grpc-web:1.5.0
google-protobuf:3.21.4

In Envoy's log, when 9188 bytes are returned, the test case does not report an error. When 16583 bytes are returned, an error is reported.

@kobofare Hi, thanks for the report!

I'm wondering if you could share some code snippets and your test setup configs (e.g. maybe with docker as well), so it could help us understand the issue?

Are you talking to a real grpc server behind envoy?

It's rather difficult for me to make out what exactly is going on from the log you provided :)

[kobofare]

yes, a real grpc server, this is a vitest config:

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    globals: true,
    environment: "jsdom",
  },
})

[kobofare]

js client code:

export class AssetProvider {
  constructor(authenticate, provider) {
    this.authenticate = authenticate
    this.provider = provider
    this.client = new AssetClient(this.provider.extend.proxy)
  }

  search(format, page, pageSize) {
    return new Promise(async (resolve, reject) => {
      const method = '/yeying.api.asset.Asset/Search'
      const body = new SearchRequestBody()
      body.setFormat(typeof format === 'string' ? convertDigitalFormatFrom(format) : format)
      body.setPage(page)
      body.setPagesize(pageSize)

      let header
      try {
        header = await this.authenticate.createHeader(method, body)
      } catch (err) {
        console.error('Fail to create header for searching asset', err)
        return reject(err)
      }

      const request = new SearchRequest()
      request.setHeader(header)
      request.setBody(body)

      this.client.search(request, undefined, (err, res) => {
        this.doSearchResponse(method, err, res, resolve, reject)
      })
    })
  }
}
