java.util.NoSuchElementException: No batch importers found

[boydkelly]

Hi, I'm new to neo4j and got a database up on 4.4.   I upgraded it to 5.1 and ran into this error importing tsv files.  This worked fine under 4.4; I just had to update the syntax.   I reduced the tsv files to a single file and single line.   csvclean reports no errors.  I previously used --delimiter="\t", but that doesn't work here either. Is it maybe just some settting I overlooked???  Thanks!!

import.sh

neo4j-admin database import incremental --delimiter=TAB --force \
        --nodes import/neo_hw.tsv

neo_hw.tsv

text:ID	orth:string	freq:int	:LABEL
á	[ á,a ] 	54	Headword

oh well....   I was able to do this with cypher instead.   Maybe this is no longer supported in the community version???   

[mandeep]

I am facing the same problem
Is incremental import supported in the community version?
