After upgrade from 8.3.1 to 8.4.1 Canvas reveal images only displaying exclamation mark. I've tried many different ways to fix this but nothing worked.
All my reveal images using sql like
select case when count(host.name) > 0 then 1 else 0 end as status from .....
if no documnet found the rusult is "No documnet Found" It is same both 8.3.1 and 8.4.1 but if there are documnts the sql result for the 8.3.1 is
1 but 8.4.1 returning
1 1 1 ...
I've also upgrade 8.4.1 to 8.4.3 but nothing changed.
