QlikView - API - SaveDocumentTask - updated between V12.10 and V12.8

[delpherv]

We migrated our QlikView server from v12.10 to V12.8 but in this new version, the API SOAP "SaveDocumentTask" is KO.

We have the error bellow

"La référence d'objet n'est pas définie à une instance d'un objet"

"HTTP/1.1 500 Internal Server Error[\r][\n]"

Do you know what it's modified in this API?

Thank you for your reply

I have a mistake in my post.

We migrate our QlikView Server from v12.10 SR6 to the last version V12.60.

Thank you for your reply
