Error: Subreport could not be shown. Sub Report works in Preview - but not when deployed

Question

I have a main report that runs multiple sub-reports. One of my sub reports runs perfectly fine in Preview, but when I deploy the report and run it from the browser, i simply get:

Error: Subreport could not be shown.

I've done some research and I am still not sure what the issue is. I've tried it in different browsers, my data sources for both the main report and sub report use the same shared data sources. And the main report and the parameters seem to pass fine (since it works in preview, I am assuming).

The error doesn't tell me much - has anyone else had this issue? Or any ideas how to debug? Many thanks!

Answer 1

Issue resolved. I needed to deploy my subreport as well, not just build.
