Python 在OpenShift V3中使用REST api上载图像时出现类型错误

我有一个通过RESTAPI接受图像的。我在本地使用测试了该api，它在图像上传方面工作得非常好。后来我将它部署在OpenShift V3上，当我尝试使用POSTMAN上传过程时，它说

服务器回溯

注意：我可以通过DRF可浏览api完成上传过程。首先，我要感谢@。实际上是邮递员的工具造成了这个问题。我使用Python的请求库测试了OpenShift-V3API。成功了：）
我使用的代码

import requests
from requests.auth import HTTPBasicAuth

url = 'http://django-psql-persistent-sampledjangoex.44fs.preview.openshiftapps.com/myapp/sample/'
filess = {'image': open('sampleImage.png', 'rb')}
r = requests.post(url,data={'name': 'value1', 'number': 12573474},auth=HTTPBasicAuth('admin', 'admin'),files=filess)

截图没用。请提供服务器回溯。你能提供你的代码吗？@Raz我用回溯更新了问题，请检查一下out@C在处理另一个异常时，您可以发现源代码看起来像是有异常。尝试调试这一行：

response=self.process\u exception\u by\u middleware（e，request）

in/opt/app root/src/.local/lib/python3.5/site-packages/django/core/handlers/base.py。获取

e

的值。这是最初的例外。Django试图渲染它，但失败了。
