title: Material-UI AutoComplete freeSolo in Form

  <p>As you can see in this SandBox, I'm using Material AutoComplete as a multiple input with free options. The component should return to Formik [&quot;term1&quot;,&quot;term2&quot;,&quot;term3&quot;] and the user can see each string as a label in a Chip. This will be used as filters in a search.
  This all happens, but only if the input is already in InitialValues. If the user does an input manually and press enter or tab it craches in a error &quot;value.map&quot; is not a function.
  The error points to this line in the material autocomplete component code</p>
  <p>&quot;getInputProps = _useAutocomplete.getInputProps,&quot;</p>
  <p>Does anyone has any ideia on how to make AutoComplete and Forms work together?</p>
