Conversion from Confluence fails without visible error message #318

Closed ClemensRobbenhaar closed 3 weeks ago

ClemensRobbenhaar commented 1 month ago

In at least one case diagrams imported from Confluence cannot be converted: pressing the "Convert" button produces an empty diagram. In the log file there is an exception:

I cut off the rest as this seems unrelated to the conversion problem.

(Unfortunately I cannot add the diagram triggering the error as the data is confidential.)

Actually this bug report should have been for the "Pro Macros", I see, as the conversion of diagrams from confluence is handled there.
