Specific invalid type breaks Form instead of rendering UnsupportedFieldTemplate

[jroebu14]

Prerequisites

• I have searched the existing issues
• I understand that providing a SSCCE example is tremendously useful to the maintainers.
• I have read the documentation
• Ideally, I'm providing a sample JSFiddle, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

core

Version

5.x

Current Behavior

There is a bug where Form won't render the UnsupportedFieldTemplate and instead break the app if the schema type is an array with the first element being a string or a number e.g.:

• { type: "unsupported type" } -> renders the UnsupportedFieldTemplate
• { type: ["unsupported type", "string"] } -> renders the UnsupportedFieldTemplate
• { type: ["string", "unsupported type"] } -> breaks the form
• { type: ["number", "unsupported type"] } -> breaks the form

Live examples of this below:

Unsupported schema type works

• https://codesandbox.io/s/unsupportedfieldtemplate-works-r6gxgk?file=/src/App.tsx
• https://codesandbox.io/s/unsupportedfieldtemplate-works-ksfdnq?file=/src/App.tsx

Unsupported schema type does not work

• https://codesandbox.io/s/unsupportedfieldtemplate-does-not-work-z7cwd2?file=/src/App.tsx

Expected Behavior

When the schema type is unsupported in any way it should render the UnsupportedFieldTemplate and not break the Form.

This should include e.g.:

• { type: ["string", "unsupported type"] }
• { type: ["number", "unsupported type"] }

Steps To Reproduce

Create a form with the following schema

{
  title: "Test form",
  type: ["string", "unsupported type"]
};

e.g.:

• https://codesandbox.io/s/unsupportedfieldtemplate-does-not-work-z7cwd2?file=/src/App.tsx

Observe that UnsupportedFieldTemplate does not render and the app/Form throws an exception.

Environment

- OS: Mac 13.5.1
- Node: 18.6.0

@jroebu14 Interesting that ordering is making a difference. Is this something you are willing to try and fix? We maintainers are pretty busy with our regular jobs and have maybe 2 hours a week to spend on fixes

@heath-freenome yeh I'm happy to try and fix. I had a look and I think I know where the issue is. I'll try and post a PR very soon.
