Hi,

I have an IFlow in CPI with a Request Reply that send a POST request to an external web server, the interface is working fine for small messages. Problem comes when the body is long, the server returns with 500 - Internal Server Error: 

<html>
<head><title>500 Internal Server Error</title></head>
<body bgcolor="white">
<center><h1>500 Internal Server Error</h1></center>
<hr><center>nginx</center>
</body>
</html>

1 error message example that I check has the Content-Length as 8559 (~9kb). But when the same payload/content is sent from Postman to the web server, the server returns 200, no error.
What could possibly wrong?

Thank you.

Hi,

I realize, the request will have this error when the server receives certain data length which is sent with header:

Transfer-Encoding: chunked
Sap-Passport: 2A5448xxxxxx
if 1 of those header is omitted, the request can be processed by the server. Is there a way to disable chunking in HTTP request?


Thank you.

Hello,

Could this be due to the limit mentioned in following document where they say HTTP adapter can only pass 8KB of the header parameter? (BTW: URL endpoint is also part of request header)

https://help.sap.com/viewer/368c481cd6954bdfa5d0435479fd4eaf/Cloud/en-US/03b32eb2c5c249f0a59bcd27c44...

If thats the case then there is a hardstop and you need to split your URL into small chunk.

Hi,

I realize that the request will be error if the request is sent with the Condition: Data is sent in Chunked & there is a Sap-Passport in the header.
Is there a way to disable chunking in HTTP request?
