eslint-plugin-import: import/no-relative-parent-imports report incorrectly in 2.20.1

In version 2.20.1, I start to get errors like:

Relative imports from parent directories are not allowed. Please either pass what ...

for

import React from 'react';

The problem did not occur in 2.20.0.

I use eslint-typescript but since this used to work in 2.20.0 I doubt that this has anything to do with that.

My .eslintrc.js looks like this

parser: '@typescript-eslint/parser',
parserOptions: {
  project: path.resolve(__dirname, './tsconfig.json')
},
plugins: [
  'react',
  'react-hooks'
],
extends: [
  'plugin:@typescript-eslint/recommended',
  'plugin:react/recommended',
  'plugin:import/errors',
  'plugin:import/warnings',
  'plugin:import/typescripts',
]
