If you are working with TypeScript and the office-ui-fabric-react library, you may come across the error message:

Interface 'ITooltipProps' incorrectly extends interface 'HTMLAttributes'

This error typically occurs when you are trying to use the Tooltip component from the office-ui-fabric-react library and there is a mismatch between the props defined in your code and the expected props of the component.

Fortunately, there are a few solutions to resolve this error:

Solution 1: Update the TypeScript version

One possible solution is to update your TypeScript version to the latest stable release. Sometimes, this error can occur due to compatibility issues between the version of TypeScript you are using and the office-ui-fabric-react library.

Code:

// Update your TypeScript version in package.json
"devDependencies": {
  "typescript": "^4.3.5"
}

Solution 2: Use type assertions

If updating the TypeScript version doesn’t resolve the error, you can try using type assertions to explicitly define the props of the Tooltip component.

Code:

import { Tooltip, ITooltipProps } from 'office-ui-fabric-react';

const tooltipProps: ITooltipProps = {
  // Define your props here
  ...
} as ITooltipProps;

Solution 3: Extend the correct interface

In some cases, the error may occur because you are extending the wrong interface in your code. Make sure you are extending the correct interface for the Tooltip component.

Code:

import { TooltipHost, TooltipHostProps } from 'office-ui-fabric-react';

interface ICustomTooltipProps extends TooltipHostProps {
  // Define your custom props here
  ...
}

By following these solutions, you should be able to resolve the error message Interface 'ITooltipProps' incorrectly extends interface 'HTMLAttributes' and continue working with the office-ui-fabric-react library seamlessly.
