Internal Error occurs


I use balsamiq on confluence.

When I use, the error occurs like this with red screen.

Internal Error
Build number : plugins-58
Assertion Failed : undefined

After Error, I can not go back to page.

I don’t know why this error occurs


Hi @jaekwan.yoo and sorry for the trouble today.

It looks like you’re not on the latest version of Balsamiq Wireframes for Confluence Server. Would you mind updating to the latest one and giving this another try?
