original file name: Codeium Chat - qNjoToMu0i76dpWCLluURE96JzYiq5Aa.md summary: The user encountered a TypeScript error where a ref object of type RefObject<HTMLElement> was not assignable to a specific type LegacyRef<HTMLDivElement>. The missing property 'align' in type 'HTMLElement' was required in type 'HTMLDivElement'. To resolve this, the user was advised to explicitly type the ref using the as keyword to convert it to the expected type React.RefObject<HTMLDivElement>. date: 2024-05-14T12:40

Explain problem: Type 'RefObject<HTMLElement>' is not assignable to type 'LegacyRef<HTMLDivElement> | undefined'. Type 'RefObject<HTMLElement>' is not assignable to type 'RefObject<HTMLDivElement>'. Property 'align' is missing in type 'HTMLElement' but required in type 'HTMLDivElement'.

The issue "Type 'RefObject' is not assignable to type 'LegacyRef | undefined'. Type 'RefObject' is not assignable to type 'RefObject'. Property 'align' is missing in type 'HTMLElement' but required in type 'HTMLDivElement'." is because the ref attribute is expecting a specific type of element (HTMLDivElement), but the provided ref (this.terminalElementRef) is of type RefObject<HTMLElement>. To fix this, you can explicitly type the ref using as keyword to convert it to the expected type like this:

<div
  ref={this.terminalElementRef as React.RefObject<HTMLDivElement>}
  id={TerminalCssClasses.Terminal}
  className={TerminalCssClasses.Terminal}
/>

This will ensure that the ref is of the correct type (HTMLDivElement) as expected by the div element.
