Material-ui Autocomplete warning The value provided to Autocomplete is invalid

Basically the reason why you get the warning is a default implementation of getOptionSelected in version 4.x.x: getOptionSelected = (option, value) => option === value In your case, selecting a value the following comparison happens: // option === value: {id:1, name:"test"} === {id:1, name:"test"} // false Obviously, it can be true in some circumstances.
