It would be nice to mention the reason why this issue was closed.

[Bhupesh-V]

The bug was actually in the parameters being passed :sweat_smile: The function generateTag() returns 2 values title and a list of values.But the order of returning the said value was different generateTags[0] gives tags and generateTags[1] gives the title of tutorial.

title, tagList = generateTags(request.data['link'])

Instead it should have been

tagList, title = generateTags(request.data['link'])
