ERROR with z_sendmany command

I’m failing to send zcash, here it is the error from debug.log
z_sendmany finished (status=failed, error=Selected input notes do not share the same anchor)

Look at the debug.log file.

z_sendmany finished (status=failed, error=Selected input notes do not share the same anchor)
should I reindex?

You could try starting a rescan first to see if that fixes the problem by passing in the -rescan flag when you restart the node, if your wallet got into a strange state that could clean it up and it’ll be substantially faster than a reindex.
