Warning: Received true for a non-boolean attribute custom

[cxgreat2014]

Why custom attr in here?

react-jsonschema-form/packages/bootstrap-4/src/SelectWidget/SelectWidget.tsx

Line 85 in 3ec17f1

custom

my jsonschema : playground

it causes error:

react-dom.development.js:67 Warning: Received `true` for a non-boolean attribute `custom`.

If you want to write it to the DOM, pass a string instead: custom="true" or custom={value.toString()}.
