React + TypeScript error: No overload matches this call

I am receiving a massive error when mapping through an array like:

// Home.tsx

  render() {
    const { inputs, outputs, expectedOutputs } = this.state;
    return (
        <ContentContainer>
          {inputs.map((input, i) => {
            return (
              <TestRow
                key={i}
                rowNumber={i}
                xml={inputs[i].xml}
                desc={inputs[i].desc}
                output={outputs[i]}
                expectedOutput={expectedOutputs[i]}
                handleTextAreaUpdate={this.handleTextAreaUpdate}
              />
            );
          })}
        </ContentContainer>
    );

// TestRow.tsx

interface TestRowProps {
  xml: string;
  desc: string;
  output: string;
  expectedOutput: string;
  rowNumber: number;
}

class TestRow extends Component<TestRowProps, {}> {
  textArea: any;

the error is:

No overload matches this call. Overload 1 of 2, '(props: Readonly): TestRow', gave the following error.

    Type '{ key: number; rowNumber: number; xml: string; desc: string; output: never; expectedOutput: string; handleTextAreaUpdate: (e: { target: { value: string; }; }, column: number, rowNumber: number) => void; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<TestRow> & Readonly<TestRowProps> & Readonly<{ children?: ReactNode; }>'.
      Property 'handleTextAreaUpdate' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<TestRow> & Readonly<TestRowProps> & Readonly<{ children?: ReactNode; }>'.

You are probably missing the return inside the function. I had the same issue, but realized the export function didn't have any return.

in the error message, you can find the problem. Property 'handleTextAreaUpdate' does not exist on type means that you should define a property for handleTextAreaUpdate in the TestRowProps interface.
