await getReader()

[drzraf]

From experiments, getReader() may not be immediately ready (at least in case a lot of input data is to be compression).
In these case, the first await reader.read() / readBytes() would return undefined unless we explicitely waited for the reader.

Ehm, that's really strange. Do you have a code example of this happening?

In any case, getReader doesn't return a Promise, so it shouldn't need await - if it does, it's broken and should probably be fixed somewhere else.

Sorry, the origin of my problem was obviously distinct.
I was firing readByte() before { openpgp.encrypt() & stream.getReader() } could actually complete.
