I am having trouble finding the correct way to define a regexp validator for a plug-in's properties.schema file.

I tried this:

    "scormid": {
        "type": "string",
        "required": true,
        "title": "SCORM ID",
        "default": "",
        "inputType": "Text",
        "validators": [/[a-zA-Z][a-zA-Z0-9_.-]*/]
    },

but it says "Plugin upload failed, Error: Failed to parse schema for package".

I tried to replace it with the example in the docs:

        "validators": [/foo/],

but this gives me the same error.

I also tried the extended version from the Backbone doc, but same result.
