We are currently performing migration from 5.6 to 6.4 but we need to support an application in AEM 5.6 to send a request to Forms 6.4 to generate a PDF. Initially we were generating using 6.2 but now we are moving to 6.4.
I am able to generate a PDF if i request it from AEM 6.4 but i am getting an error if i request it from AEM5.6
Below is the error. Any help would be appreciated.
