Error while Image Annotation

Hi there,
Whenever I upload a few images to annotate them and when I click the next image arrow at the top center, the following error pops up and after I click anything (ok or close) it just starts loading and shows a loading icon in place of the next arrow icon. It started happening a few hours ago.

Hi @Zohaib_Munir, can you report this bug on our bug tracker so I can get it forwarded to our development team?
