Unexpected token during transformation

Compiling the following type results in a syntax error:

Codegen.TypeScriptToModel.Generate(`export type T = [string, ...string[]]`);

The thrown error:

    ...Type.Rest(string[])
                        ^

SyntaxError: Unexpected token ']'

The TypeScript type is also a generated one (from JSON schema, where the compiler defines a list with minItems: 1 like this), so I can probably find a workaround by relaxing the JSON schema.
