Material Autocomplete does not work with InputProps

Question

I am trying to change the border of my TextField that is rendered through my Autocomplete, but when I add the InputProps prop, the Autocomplete no longer renders Chips

<Autocomplete
    multiple
    freeSolo
    options={options}
    renderTags={(value, { className, onDelete }) =>
        value.map((option, index) => (
            <Chip
                key={index}
                variant="outlined"
                data-tag-index={index}
                tabIndex={-1}
                label={option}
                className={className}
                color="secondary"
                onDelete={onDelete}
            />
        ))
    }
    renderInput={(params) => (
        <TextField
            {...params}
            id={id}
            className={textFieldStyles.searchField}
            label={label}
            value={value}
            onChange={onChange}
            variant="outlined"
            //InputProps={{
            //     classes: {
            //         input: textFieldStyles.input,
            //         notchedOutline: textFieldStyles.notchedOutline
            //     }
            //}}
            InputLabelProps={{
                classes: {
                    root: textFieldStyles.label
                }
            }}
        />
    )}
/>

The above code works, and once I uncomment the InputProps line, the input no longer renders Chips when an item is selected or entered.

Thanks

This happens because the InputProps attribute is overriding the InputProps parameter of params, you have to merge InputProps property of params:

InputProps={{
    ...params.InputProps,
    classes: {
        input: textFieldStyles.input,
        notchedOutline: textFieldStyles.notchedOutline
    }
}}
