Cannot start Neo4j 4.0.0

[harvey_nguyen]

I have just installed Neo4j 4.0.0 Enterprise edition by using Neo4j Debian package. At the first time I started, It run properly. After that, I stop service to install APOC and Algo plugins and started it again. The error has occured

Argument `nodeIds` at position 0 in `list` with
type `List` cannot be converted to a Neo4j type: Default value `` could not be parsed as a LIST? OF INTEGER?

What's happened with my Neo4j and how to fix it ?
Thank you

Goodevening,
Good it be that the APOC and/or ALGO plugin is NOT version 4.xxx?

Yours kindly

Hi Harvey,
Graph algorithms are not compatible with 4.0 yet. I believe APOC 4.0 compatible version was released recently. Use that jar and remove graph algorithms plugin.

Thanks

If the issue persists after removal of algo plugin, also remove apoc to bisect if it's an apoc issue or something else.

Thanks @anthapu for your solution,

@stefan.armbruster I have just remove algorithms plugin and started it again. Neo4j work well.
However, I am using unionFind algorithm in 3.5 version. So I have to wait a new release for graph algorithms plugin? Are there any solutions if I want to using neo4j 4.0?

Thanks
Harvey

You'll have to wait for Algo plugin to work with 4.0. I'd guess it's a few weeks out.

Just ran into this issue myself.
