This error is occurring because, this is still using 3.4.* . This library must be update to be used with 3.5.1, which is the latest version. If you can change the syntax compatible to gremlin 3.5.1 , This error will probably won't occur.

update line 184&186 traversal_source to __ in/scripts/graphioGremlin.js

[bricaud]

A PR would be appreciated on this issue.

This fixes the error for me, however I don't know enough about the application to tell if I've fixed all the 3.5 problems, nor if I've caused any regression for older Tinkerpop versions.

[pimjansen]

Is this still an open topic? Or are there any alternatives in browser/exploring a graph database (for free) in development?

[bricaud]

I need to create an option where traversal_sourceis replaced by __ when choosing version 3.5. So here the PR is not complete, if I merge, the code wont run for people using earlier versions.

[bricaud]

I merged the PR! Thanks a lot!
