URL: https://github.com/apache/beam/pull/12551#issuecomment-673564429
@mxm How is it possible that `getContextTimerId` (used in the precondition
check and in the logic around that) does not contain key, if `String
contextTimerId = getContextTimerId(timer.getTimerId(), timer.getNamespace())`
is used for registering and cancellation of timers? There seems to be an issue
with missing timer family id, but that is not related.
