React Ajax call on load gives : “Error: Should not already be working.”

Problem : On page refreshes, the ajax calls in the componentDidMount functions throws the error : “Error: Should not already be working.”

Reason : Probably the ajax request is called before the react’s async calls framework is initialized.

Fix: Run within a timeout function
Eg –

componentDidMount() {
    setTimeout(() => {
    }, 400);
