Ngx-formly: Formly Material - Validation error message doesn't seem to show

I'm submitting a ... (check one with "x")

Current behavior

When configuring formly as follows:

{
  key: 'name',
  type: 'input',
  templateOptions: {
    label: 'Name (required)',
    required: true
  }
}

..the form is properly invalidated, but the error message doesn't display. I'm using Angular Material here.

Expected behavior

The validation message shows 😉

you have missed one small step, the error message should be defined in NgModule declaration:

    FormlyModule.forRoot({
      validationMessages: [
        { name: 'required', message: 'This field is required' },
      ],
    }),

@aitboudad Oh, I thought those are built-in, as I didn't find them in the demo examples: https://formly.dev/examples/validation/built-in-validations

Oh, stupid me...it's in the FormlyModule.forRoot 🙄

sorry 😓

no worry :smile: , a bunch of examples that cover all validation possibilities :) are there:
