Does this happen with every sonar log, or just one? If possible, it could be really useful to have the text that is shown in the exception window. If it happens again, please select the text, copy it and forward it in an email to This email address is being protected from spambots. You need JavaScript enabled to view it.
. Also, if it is an issue with one specific track, it would be useful to see it. Is there any chance you could share it (zip it up and use a file transfer such as WeTransfer and send the link to our support address)?
