Flask restful API部署在具有依赖项的Heroku上

我在Heroku上部署Flask应用程序时遇到以下错误

是的，我读了消息，但问题是我正在调用API以获得结果

from flask import request, jsonify


app = flask.Flask(__name__)
app.config["DEBUG"] = True

# Create some test data for our catalog in the form of a list of dictionaries.

@app.route('/', methods=['GET'])
def home():
    return '''<h1>WELCOME</h1>
<p>Get all pppp hhhh insterted and delected text from the word document.</p>'''

@app.route('/api', methods=['GET'])


def api_id():
    import requests
    import xmltodict
    import pprint
    import json
    from zipfile import ZipFile
    from urllib.request import urlopen
    from io import BytesIO
#     from zipfile import *
    from bs4 import BeautifulSoup
    import pandas as pd
    
    if 'Id' in request.args:
        Id = request.args['Id']
        print(type(Id))
    else:
        return "Error: No id field provided. Please specify an id."
    results = []
    url='https://bps.quickbase.com/db/****?a=API_GetRecordInfo&rid='+Id+'&fmt=structured&usertoken=****'

    response = requests.request("GET", url)
    print(response)

        Mapped_data={R_Id :Document}

        wordobj=BeautifulSoup(xml_content.decode('utf-8'),'xml')
        key_record=key
        for dl in wordobj.find_all('w:del'):
            Text=dl.text
            author=dl.get('w:author')
            Date=dl.get('w:date')
            Type='Deleted Text'
            ID=dl.get('w:id')
            ID=int(ID)
            dataDict_del = { 'Text':Text,'Author':author,'Date':Date,'Type':Type,'ID':ID,'Record_Id':key_record}
            print(dataDict_del)
            track_changed_for_del.append(dataDict_del)
        for ins in wordobj.find_all('w:ins'):

            dataDict_ins = { 'Text':Text,'Author':author,'Date':Date,'Type':Type,'ID':ID,'Record_Id':key_record}
            track_changed_for_ins.append(dataDict_ins)
        df_track_changed_ins= pd.DataFrame(track_changed_for_ins)
        df_track_changed_del= pd.DataFrame(track_changed_for_del)```

你读到那条消息了吗？看起来您只是绑定到5000，而忽略了PORT env var Heroku集合。见例。
