When generating a project document from a PowerPoint template or Testing a template, users may receive the following error:
Data at the root level is invalid. Line 1, position 1
The error usually occurs if a content item, used in either a Guided Cart or Static Content Section, has the following setting switched on.
For each Content Item(in the KS):
1) Open the Content Item.
2) File>Options>Save>Embed fonts in the file:
3) Switch the above setting to Off (ie uncheck 'Embed fonts in the file'). Save the content and save.
Note: You may have to Approve the edited Content Item.
Test your template again.
