A SAR was created for the RESTful client service provider. On
the request, the header Accept-Encoding=gzip,deflate was passed
from the client to z/OS Connect EE. z/OS Connect EE
passed this to the REST endpoint, which responded correctly.
z/OS Connect EE failed to handle the returned compressed data
resulting in an HTTP response code 500 (internal server error)
being returned. The following messages was issued:
BAQR0429W: API {0} encountered an error while processing a
request under URL {1}.
The following IOException is recorded in the z/OS Connect EE
server's FFDC directory:
Exception = java.io.IOException
Source = com.ibm.zosconnect.service.client.rest.internal.SarRes

Local fix
Send the request with header: Accept-Encoding:identify
Problem summary
****************************************************************
* USERS AFFECTED: All users of z/OS Connect EE V3.0. *
****************************************************************
* PROBLEM DESCRIPTION: HTTP response code 500 and message *
* BAQR0429W are returned when an *
* Accept-Encoding:gzip,deflate header is *
* flowed. *
****************************************************************
z/OS Connect EE was passing on gzip compressed data with a valid
header to the target program, but was not able to process the
returned gzipped data.
Problem conclusion
Temporary fix
Comments
z/OS Connect EE has been changed to not forward the following
headers:
ContentType, ContentEncoding, ContentLanguage, Accept,
AcceptEncoding, AcceptLanguage
The Accept header will be set to MediaType application/json in
the flowed request.
The fix for this APAR is expected to be delivered by the PTF for
z/OS Connect EE V3.0.23.0 (PH13344).
