I have below two issues with Jaspersoft, was trying in all avenues but could not resolve.
We were on Clarity 14.2 and Jasper 5.6.1 On premise. Migrating to Clarity 15.1 and Jasper 6.2.1 and also migrating servers to AWS. having below issue any inputs are really appreciated.
1. Very few reports are throwing this error, while running the report from UI. when scheduled running fine. also the CA PPM BEAN and CA PPM DWH BEAN are showing as test failed when i login to direct url (/reportservice). There is nothing getting logged in the Jasperlogs.
Error DetailsHTML response error code: 502, error
HTML response was: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
The proxy server received an invalid response from an upstream server.The proxy server could not handle the request POST /reportservice/flow.html.
Reason: Error reading from remote server
2. Output to Host File system option not working | Jaspersoft Community
The reason you are getting this error is because your reverse proxy is blocking the error codes, some reports which are big and more than 500 pages its getting blocked and rather than showing the error code its shows the error. To fix the same you need to work with network team and turn off ProxyErrorOverride to off
This is the recommend setting after change...
<IfModule proxy_module> ProxyErrorOverride On ....... ....... </IfModule>
<VirtualHost *:8081> ProxyErrorOverride Off ....... ....... </VirtualHost>
<VirtualHost *:8082> ProxyErrorOverride Off ....... .......
You can see the request is getting blocked when you do a fiddler trace or browser trace.
