HTTP procedure calls during IFRS17 v09.2023 cycle runs fail randomly with a 502 Proxy Error


When you have a forward proxy server that is part of the SAS infrastructure deployment, IFRS17 cycles run randomly, and the cycles fail with the following error:

MPRINT(IRM_REST_REQUEST):   proc http url =

"https://<hostname>:443/SASRiskGovernanceFramework/rest/rmc/cycles/61197?&ticket=ST-2919-AbmRIR-iiYuJhIH10ecHHqL-O58-

frdevsaw27" method = "PATCH" headerin = patchHin in = cycleBdy headerout = __hout_ out = __out__ ct = "application/json"

clear_cache ;

[...]

> PATCH /SASRiskGovernanceFramework/rest/rmc/cycles/61197?&ticket=ST-2919-AbmRIR-iiYuJhIH10ecHHqL-O58-frdevsaw27 HTTP/1.1

[...]

< HTTP/1.1 502 Proxy Error

[...]

NOTE: 502 Bad Gateway

NOTE: PROCEDURE HTTP used

Workaround

To circumvent this issue, implement or append the following parameter within the Apache Server sas.conf file:

SetEnv   proxy-initial-not-pooled 1

ProxyRequests  off
