Cloud Run/Cloud Run Functions集成Cloud Pub/Sub时出现grpc超时警告及构建错误的求助

我正在开发一个简单的Web应用，它接收HTTP POST请求并触发Cloud Pub/Sub事件。在没有集成Pub/Sub的时候，应用部署完全正常，我也能正常访问端点。

我分别通过Cloud Run Functions控制台和Cloud Run控制台部署过示例函数，两种方式都能正常部署默认的Hello World示例，没有任何问题。

现在我要添加Pub/Sub功能，做了这些操作：

• 在requirements.txt里添加了google-cloud-pubsub依赖
• 在代码中引入了Pub/Sub客户端
• 通过控制台创建了Pub/Sub主题

现在我的代码是这样的：

import json
import os
import functions_framework
from google.cloud import pubsub_v1

PROJECT_ID = "my project"
publisher = pubsub_v1.PublisherClient()

@functions_framework.http
def hello_http(request):
    """HTTP Cloud Function.
    Args:
        request (flask.Request): The request object.
        <https://flask.palletsprojects.com/en/1.1.x/api/#incoming-request-data>
    Returns:
        The response text, or any set of values that can be turned into a
        Response object using `make_response`
        <https://flask.palletsprojects.com/en/1.1.x/api/#flask.make_response>.
    """
    request_json = request.get_json(silent=True)
    request_args = request.args

    topic_name = 'projects/{project_id}/topics/{topic}'.format(
        project_id=PROJECT_ID,
        topic='test-topic',
    )
    message = {
        'key': 'value',
        'info': 'This is a test message'
    }
    future = publisher.publish(topic_name, json.dumps(message).encode("utf-8"))
    future.result()

    if request_json and 'name' in request_json:
        name = request_json['name']
    elif request_args and 'name' in request_args:
        name = request_args['name']
    else:
        name = 'World'
    return 'Hello {}!'.format(name)

现在我在控制台里总会看到这些警告，想知道这是什么意思：

WARNING: All log messages before absl::InitializeLog() is called are written to STDERR
E0000 00:00:1734272617.454893 1 init.cc:229] grpc_wait_for_shutdown_with_timeout() timed out.

另外，在Google Cloud Run测试控制台里还会出现一些看起来和构建相关的奇怪错误，有时候报错有时候又不报错，比如：

[9:47:15 PM] - Preparing function sources ...
[9:47:15 PM] - Loading new function sources ...
[9:47:22 PM] - Starting function...
[9:47:22 PM] - WARNING: All log messages before absl::InitializeLog() is called are written to STDERR

/bin/sh: 2c3d685a15e9: not found
/bin/sh: 2c3d685a15e9: not found

有没有人遇到过类似的问题，能帮我解释下这些警告和错误的原因，以及怎么解决吗？
