custom functions with json schema

[aleesalami932]

i am using formily with antd5 and json schema to build dynamic forms i want to pass custom functions for my use cases in "x-reactions" run and i am facing issues doing that
here's an example:
"x-reactions": [ { dependencies: [ { property: "value", type: "string", source: "chain", name: "chain", }, ], fulfill: { state: { value: '{{""}}', }, }, }, { dependencies: [ { property: "value", type: "any", source: "chain", name: "chainValue", }, ], fulfill: { run: "$effect(()=>{\r\n $self.loading = true\r\n fetch('data.json')\r\n .then(response=>response.json())\r\n .then(({ data })=>{\r\n $self.loading = false\r\n $self.dataSource = data[$deps.chainValue]\r\n },()=>{\r\n $self.loading = false\r\n })\r\n},[ $deps.chainValue ])", }, }, { dependencies: [ { property: "value", type: "string", source: "chain", name: "chain", }, { property: "modified", type: "boolean", source: "chain", name: "chainModified", }, ], fulfill: { run: "", state: { pattern: "{{$deps.chainModified ?$deps.chain ? 'editable' : 'disabled': 'disabled'}}", }, }, }, ],
instead of the fetch('data.json') i want to pass another function that returns a promise but when i pass my function i am a getting an error that the function is not defined
