React does not recognize the `InputProps` prop on a DOM element

Question

Warning: React does not recognize the InputProps prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase inputprops instead. If you accidentally passed it from a parent component, remove it from the DOM element.

I don't understand what I'm doing wrong. And I've seen many similar issues like this. But I couldn't see a proper solution.

<TextField
  {...input}
  {...rest}
  name={input.name}
  inputRef={inputRef}
  autoFocus={inputRef.current === document.activeElement}
  disabled={disabled || false}
  multiline={rowCount ? true : false}
  style={{
    width: "100%",
  }}
  onChange={(event) => {
    input.onChange(event.target.value);
  }}
  {...(hesapla
    ? {
        onBlur: (e) => {
          hesapla({ name: input.name, value: input.value });
        },
        onKeyDown: (e) => {
          if (e.key === "Enter") {
            hesapla({ name: input.name, value: input.value });
            e.preventDefault();
          }
        },
      }
    : {})}
  InputProps={{
    classes,
    ...(inputComponent ? { inputComponent: inputComponent } : {}),
    ...(endAdornment ? { endAdornment: endAdornment } : {}),
  }}
  inputProps={{
    style: {
      maxHeight: (rowCount * 16).toString() + "px",
      overflow: "auto",
      ...(rightJustify ? { textAlign: "end" } : {}),
      ...(!readOnly && hesapla
        ? { fontWeight: "bold", borderBottom: "2px solid" }
        : {}),
    },
    readOnly: readOnly ? readOnly : false,
  }}
></TextField>

Answer 1

the issue is that you are using inputProps instead of InputProps

Answer 2

Those who came to this post and using MUI Autocomplete, the culprit is your input element. Autocomplete widget by default expects you to use Textfield Input as of now. (the params passed to the input element are only available on Textfield widget, see image below).

TextField

Input Base

If you want to use any other input field, extract the props from the params passed and pass the desired props to your input element. Like, i used InputBase component and passed only inputProps not InputProps to it. You can find the available properties in MUI documentation.
