使用Python后端抖动中的云函数失败{code：INTERNAL，详细信息：null，消息：INTERNAL}）

Question

尽管在使用GCP功能GUI进行测试时该功能可以完美运行，但我的函数中始终出现此错误。我用于在线测试的输入形式为{“ url”：“ URL_STRING”}。

我的python代码如下：

from datetime import datetime
from time import time, mktime
import pytz
import os
from os import path
import nltk
root = os.path.dirname(path.abspath(__file__))
download_dir = os.path.join(root,'my_nltk_dir')
os.chdir(download_dir)
nltk.data.load(
    os.path.join(download_dir,'tokenizers/punkt/english.pickle')
)
nltk.data.load(
    os.path.join(download_dir,'tokenizers/punkt/PY3/english.pickle')
)
// WORKAROUND TO REDUCE DEADLINE ERROR MARGINALLY

def Parser(url):
if 'String1' in url:
        source = 'string1'
    elif 'String2' in url:
        source = 'string2'
    elif 'String3' in url:
        source = 'string3'
    elif 'String4' in url:
        source = 'string4'
    <PARSING CODE FOR DATETIME, IMG, SOURCE, KEYWORDS>
    return jsonify(source, datetime, imageurl,keywords)

def invoke_parse(request):
    request_json = request.get_json(silent=True)
    file = Parser(request_json['url'])
    return file

我的Flutter函数调用使用cloud_functions依赖项，如下所示：

              onPressed: () async {
//------------------FUNCTION CALL---------------------------------------------
                final HttpsCallable callable = CloudFunctions(region:"region")
                    .getHttpsCallable(functionName: "function name",)..timeout = const Duration(seconds: 540); 
// MASSIVE TIMEOUT TO PREVENT DEADLINE ERROR WHICH STILL HAPPENS AT ROUGHLY 10 SECS
                try {
                  dynamic response = await callable.call(<String, dynamic>{
                    'url': urlController.text,
                  });
                  setState(() {
                    print(response.data.toString());
                    print(publishedAt_en = DateTime.now().toString());
                  });
                } on CloudFunctionsException catch (e) {
                  print('Caught Firebase Functions Exception');
                  print(e.code);
                  print(e.message);
                  print(e.details);
                } catch (e) {
                  print('Caught Generic Exception');
                  print(e.code);
                  print(e.message);
                  print(e.details);
                }
              }
