@yuriwoof Thanks for the bug report. This happens when there is one item returned. We have a different way to fix this and will get it pushed out soon.

The fix you have in your code will clear the advisories array, I would check your advisories and make sure everything is showing up.

@yuriwoof I am unable to reproduce this error even with one item returned. Can you reach out to me internally and we can investigate this further?

Thank you!

[yuriwoof]

@kpoineal sure! I'll contact you internally.
