Neo4j Bloom Error Message

Neo4j Graph Platform Neo4j Visualization Library (NVL)

Hello,
Recently started learning about graph database and using neo4j desktop 4 free version. I also got the activation key for neo4j bloom. Every time I open bloom, I receive the below message:

Cannot read property 'toUpperCase' of undefined

Can someone please help me rectify the issue?

could you please describe to what database your bloom installation connects?

Bloom is not yet ready to work with Neo4j 4.0. If you depend on Bloom you have to stick with Neo4j 3.5 for some time.
