panic error on indexer

Hi,

Hope you are all well !

If I index several websites, after some point I have this error:

Depth: 1 - Queued: 3977
panic: runtime error: index out of range [1] with length 0

goroutine 27 [running]:
github.com/nwihardjo/SpaghettiSearch/indexer.Index(0xc00c3e0000, 0xc52be, 0xffe00, 0xc0000f4070, 0x7ffe1107d10f, 0x1d, 0x0, 0xed38f5121, 0x0, 0x0, ...)

Is there something wrong with badger ? How to fix it ? Any ideas ?

Cheers,
