submitForm ListcheckboxField doesn't work

[katarzynapawelczak]

submitForm(input: {formId: 1, data: [
{id: 1, value: "Julius"},
{id: 2, value: "julius@test.com"},
{id: 3, value: "Hello there"},
{id: 4, value: "[one,three]"}
]})

The 4th field is a list checkbox field. And I can't save data from this field through fetch API (graphql mutation through fetch api call). I have seen that Ninja Forms sends string array for this type of field, so I tried to recreate it.
