formData with an empty string is not flagged as a validation required field error message

[dagda1]

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 or a shared playground link demonstrating the issue.

What theme are you using?

material-ui

Version

^5.0.0-beta.14

Current Behavior

With the following schema:

{
  "title": "Contextualized errors",
  "type": "object",
  "required": ["firstName", "lastName"],
  "properties": {
    "firstName": {
      "type": "string",
      "title": "First name"
    },
    "lastName": {
      "type": "string",
      "title": "Last name"
    }
  }
}

And the following Form component with the firstName field set to undefined and lastName set to ''.

<div className="container-fluid">
  <Form
    validator={validator}
    schema={schema as any}
    showErrorList={false}
    noHtml5Validate
    uiSchema={{}}
    customValidate={undefined}
    formData={{
      firstName: undefined,
      lastName: ''
    }}
    omitExtraData={false}
  />
</div>

firstName is recognised as a required field validation error, but lastName is not:

Expected Behavior

Any field with an initial formData value of '' should trigger validation of required fields.

Steps To Reproduce

1. git clone git@github.com:dagda1/rjsf-example-5.git
2. yarn install
3. yarn start

I tried to create this codesandbox but I get the following error which does not happen when running the code outside codesandbox.

Error: Cannot find module 'ajv/dist/compile/codegen'

Environment

- OS:osx 12.6
- Node:16.17.0
- npm: 8.19.2

This may be a duplicate of #3260 ... Which version of the validator are you using, ajv6 or ajv8?

[dagda1]

Which version of the validator are you using, ajv6 or ajv8?

I'm using ajv8

[heath-freenome]

Then it is likely an issue we are working on fixing related #3260

[dagda1]

@heath-freenome using the @rjsf/validator-ajv6 validator has the validations working as before.

[heath-freenome]

Ok, watch #3260 and when we release the fix, go ahead and switch back to the ajv8 version. Closing this as a dup.
