I am getting this exception when trying to process a PPT file that has a chart label with two different sets of format (as seen in example attached).

Important to notice that I tested with different versions and notice that 21.1 does not produce the error but from 21.2 on it happens (test is 22.4)

@jroldan1,
Thank you for contacting support.

It will take me some time to check the error you are facing. We will reply to you as soon as possible.

#3

Thanks for the reply, I forgot to add that if in PowerPoint you select the chart’s label with the format and use the “Reset label text” button the exception no longer happens, thats why I think is related to the multiple formats

#4

@jroldan1,
Thank you for the additional information. We will get back to you a little later.

#5

@jroldan1,
Please try to isolate the problem and share a minimal code example without your application code and third-party packages.

#6

Here is the issue as isolated and minimized as possible, you’ll see a main method TestMethod that does the loading and saving of the file (when the issue is triggered). The only process I have to do before that is some text substitution critical for the operation. I hope this example helps, if you need something else please let me knowAspose22.4bug.zip (68.0 KB)
