We are seeing this error message
Type Error undefined is not an object evalating s.segmentIndex
Look associated to cleanStreamMap_() {
if (stream.segmentIndex && !stream.segmentIndex.isEmpty()) {
Where stream is undefined....

Are you planning send a PR to fix it?
If i found the issue yes

Look releated to the refactor here d8a14b0#diff-abddb185c4fb1df35b1c9a4f11b32f2e6112c7c0d6d33c882dcca9ba583f1c13L1507
and here too
#7301

Where we expect to have stream still available as part of the map
But indexStreamMap_ is not retaining the stream only the ref.
The code added was suggesting that the stream will exist in the stream map but can be deleted by
delete this.streamMap_[contextId];
if we have double occurence of the context id as part of the indexStreamMap_[pid]

Look like my first implementation had move to something more complex with more expectation.
cleanStreamMap_ was designed to clean any duplication or retention

@avelad just let me know your thought as you refactor the code
