Flask app when deployed to azure web service giving incomplete response content

Harsh Chaudhary 1

I am using flask to make a proxy. I am hitting an api endoint from flask POST endpoint, sending back response. This process is working properly without any issue on my local machine. When I deployed the same to azure web service, sometimes it is sending me incomplete content in response.

Can you please suggest me anything ?

Can you clarify the following @Harsh Chaudhary :

How is your API service deployed and configured?

How is the content incomplete?

While running flask post endpoint locally (on localhost):
Request

POST http://127.0.0.1:5000/ HTTP/1.1  
Content-Type: text/xml  
  
<IDORequest ProtocolVersion="5.02" SessionID="">  
  <RequestHeader Type="OpenSession"/>  
</IDORequest>

Response

<IDOResponse ProtocolVersion="6.01" SessionID="84279383847967388798392898">  
  <ResponseHeader Type="OpenSession">  
    <InitiatorType/>

    <SourceConfig/>

While running deployed version of flask endpoint (https://<myappservicename>.azurewebsites.net/):
Request

POST https://<myappservicename>.azurewebsites.net/ HTTP/1.1  
Content-Type: text/xml  
  
<IDORequest ProtocolVersion="5.02" SessionID="">  
  <RequestHeader Type="OpenSession"/>  
</IDORequest>

Response

<IDOResponse ProtocolVersion="6.01" SessionID="3872944628799">  
  <ResponseHeader Type="OpenSession">  
    <InitiatorType/>  
    <InitiatorName/>  
    <SourceName/>  
    <SourceConfig/>  
    <TargetName/>  
    <TargetConfig/>  
    <Resp

The response coming above is incomplete. I also saw that sometimes it works fine, but most of the time i get this incomplete response.

How my app service is deployed
I created my app service manually on azure portal with basic tier. The configuration is attached as screenshot below:

I have deployed code through vscode.

Thanks for information @Harsh Chaudhary . It was really helpful, but I can't think of any reason the response would be truncated like that. Please respond to the private message below so I can work more closely with you regarding this matter.
