Determine this is the right repository

• I determined this is the correct repository in which to report this bug.

Summary of the issue

Context

Using the TextToSpeechLongAudioSynthesizeAsyncClient to produce a Neural2 voice file results in an gRPC error.

Expected Behavior:
The speech file to successfully land in the provided GCP storage bucket.

Actual Behavior:
The client produces the following error:

 google.api_core.exceptions.ResourceExhausted: 429 received metadata size exceeds hard limit (18013 vs. 16384);  grpc-status:44B grpc-message:17969B

API client name and version

google-cloud-texttospeech 2.17.2

Reproduction steps: code

import os

import pytest
from google.api_core.client_options import ClientOptions
from google.cloud import texttospeech
from google.protobuf.message import Message


@pytest.mark.asyncio
async def test_metadata_error(pytestconfig, config):
    ssml = read_test_document(pytestconfig, "tests/resources/problems/tts-metadata-error.txt")
    client = texttospeech.TextToSpeechLongAudioSynthesizeAsyncClient(
        client_options=ClientOptions(quota_project_id=config.gcp_project_id)
    )
    # noinspection PyTypeChecker
    tts_input = texttospeech.SynthesisInput(ssml=ssml)
    # noinspection PyTypeChecker
    audio_config = texttospeech.AudioConfig(
        audio_encoding=texttospeech.AudioEncoding.LINEAR16
    )
    # noinspection PyTypeChecker
    voice = texttospeech.VoiceSelectionParams(
        language_code="en-GB",
        name="en-GB-Neural2-F"
    )
    # noinspection PyTypeChecker
    request = texttospeech.SynthesizeLongAudioRequest(
        parent=f"projects/{config.gcp_project_id}/locations/us-central1",
        input=tts_input,
        audio_config=audio_config,
        voice=voice,
        output_gcs_uri=f"gs://{config.gcs_internal_bucket_name}/test/metadata_error.wav",
    )
    operation = await client.synthesize_long_audio(request=request)
    result: Message = await operation.result(timeout=300)
    assert result


def read_test_document(pytestconfig, relative_path: str) -> str:
    file_path = os.path.join(pytestconfig.rootpath, relative_path) 
    with open(file_path, "r") as file:
        return file.read()

Reproduction steps: supporting files

@mcantrell Thanks for reporting this. The error seems to be emitted from the gRPC layer. I've filed grpc/grpc#37852 which you can follow for any status updates. We will work with the folks there and investigate what the root cause is.
