Invalid prop `toolbar` supplied to `RichTextInput`

[batbyR]

For the need of my project, I have added a custom toolbar to my RichTextInput field. It worked like a charm except a console warning.

What you were expecting:
Using a custom toolbar in a RichTextInput (following quill documentation) should not print a warning in the console.

What happened instead:

I got this console warning:

Steps to reproduce:

In react-admin demo, add a custom toolbar in the TagEdit file.

Related code:

 <RichTextInput
        source="description"
        addLabel={false}
        toolbar={quillToolbarOptions}
      />

const quillToolbarOptions = {
  container: [
    [{ header: [1, 2, 3, false] }],
    ["bold", "italic", "underline", "link"],
    [{ list: "ordered" }, { list: "bullet" }],
    ["clean"],
    ["link"]
  ],
  handlers: {
    // handlers object will be merged with default handlers object
    link: function(value) {
      if (value) {
        var href = prompt("Enter the URL");
        this.quill.format("link", href);
      } else {
        this.quill.format("link", false);
      }
    }
  }
};
