Thanks for the report.

That Example works fine when run locally, it's just that it cannot be run on the playground. The run button should be disabled for these example, and this is a known issue: #9679 (website: don't show un-runnable examples as runnable)

ExampleReader is already mentioned there as one of the examples that don't work, so I'm closing here as a dup of #9679.
