I have finally updated the library after the feedback that I received at the joint user group. The code now handles all of the four sample Contentful spaces and empty spaces.
The library used the content type id as the name of the type in Neo4j. There is a mismatch in rules so I have prefixed it with “type_”. This avoids leading numbers.

You can also quote with backticks `0Abc` if you have leading numbers or other non-identifier names.
