The latest LSP-json doesn't work on ST 3.

As per report on sublimelsp/LSP-css#46 (comment)

I haven't pinpointed which version of lsp-json breaks ST3 compatibility, but the error mentioned above is similar to these issues:

sublimelsp/LSP-html#45
sublimelsp/LSP-css#46

Where both html / css languages introduced a similar change before breaking ST3 compatibility :

• feat: implement support for css.customData (Implement support for css.customData LSP-css#44)
• feat: implement support for html.customData (Implement support for html.customData LSP-html#38)

Hope this helps, thanks!

Addressed. ST3 is now served an older version of LSP-json that doesn't have ST4-specific code.
