We developed a Soap Integration layer between our product and Adobe Elements Server, using the trial version of Adobe Elements 18.104.22.168.
We have tried to install this at our first customer's site. They have purchased Adobe Elements 22.214.171.124.
However, when our product tries to call the createPDF we are receiving an error stating that the sourceFilename parameter is not specified.
Checking the WSDL for createPDF, it does state this parameter is required for 126.96.36.199. However, this was never required on our 188.8.131.52 installation.
I'm guessing this has changed between the versions.
If it has changed between such a minor product version difference (and I can find no information explicitly stating such a change), I'm scared it will change and break integration everytime we need to upgrade Adobe Elements.
