JSON schema object that accepts any properties

[arthurdenner]

I want a custom field where different properties would be added to an object.
I've tried multiple things but most of them resulted in Invariant Violation - Field not found in schema: "x"

I don't know if I'm creating the wrong schema here or if it's a limitation of uniforms-bridge-json-schema, similar to #863.
EDIT: It seems like a limitation, properties are required (ref).

I'll list a few attempts here:

{
  "type": "object",
  "additionalProperties": true
}

{
  "type": "object",
  "additionalProperties": { "type": "string" }
}

{
  "type": "object",
  "additionalProperties": true,
  "patternProperties": { "^.*$": { "type": "string" } }
}

In the end, I'm trying to have an object field that will get different properties based on the implementation of the custom field. The custom field is creating fields using components from uniforms-antd such as AutoField or SelectField. Each of these is getting a name prop (e.g. <SelectField name="x" {...props} /> but then it fails with the aforementioned Invariant Violation.

This is an example of how I'm trying to implement the custom field:

function CustomField(props) {
  const options = props.anArrayOfStrings.map((value) => ({ label: value, value }));
  return <SelectField {...props} name="x" options={options} />;
}

export default connectField(CustomField);
