Sync data crashed in the middle in Kurrent coin

[kurrentproject]

I set up an iquidus explorer for Kurrent (https://bitcointalk.org/index.php?topic=1691086.0), a zerocoin/X11 coin. When I sync data with sync.js (index update), everything goes on well until block 1257, where there's a vout[1], and it crashes:

I tried to sync only with vout[0], but still there are similar errors after a few more blocks. Any suggestions? Thanks.

[kurrentproject]

this is where the Kurrent is minted into zerocoin, corresponding to a temporary destruction of the coin, where the explorer not working. Hope dev has a simple way to get around it.

[iquidus]

This is something I will need to look into further.

[zoincoin]

I have the same problem on Zoin coin. The script is locked on the first zerocoin transaction
