Repro steps
Unfortunately I don't know how to reproduce this bug. It was just logged to Sentry.
It seems like there's a logic bug here though:
https://github.com/facebook/react/blob/bd4784c8f8c6b17cf45c712db8ed8ed19a622b26/packages/react-devtools-shared/src/devtools/views/Components/TreeContext.js#L386-L416
If selectedElementIndex is null or elementIndicesWithErrorsOrWarnings is empty, then flatIndex would be 0 still– and this statement would result in an undefined entry:
prevEntry =
elementIndicesWithErrorsOrWarnings[
elementIndicesWithErrorsOrWarnings.length - 1
];How often does this bug happen?
