"should be equal to one of the allowed values" error on choice field

[jakub-zawislak]

I'm using liform-react with LiformBundle. I have a form:

$builder->add('someField', EntityType::class, [
    'label' => $this->getLabel($contact),
    'required' => false,
    'class' => 'Entity\SomeEntity',
]);

Object generated by liform:

properties: {
  someField: {
    enum: ["1", "2", "3"],
    enum_titles: ["one", "two", "three"],
    // ...
  }
}

After selecting an option, ajv returns validation error

"should be equal to one of the allowed values"

On backend there is no validation errors.

Hi, have you already found a solution? I'm encountering the same problem. Adding an empty string within both enum and enum_titles fixes the problem but also hides the placeholder :|

You can change the type to be one of either null or enum (note the quotes around "null"!):

properties: {
  someField: {
    oneOf: [
        { type: "null" },
        {
          type: "string",
          enum: ["1", "2", "3"]
         }
    ]
    // ...
  }}
