webadb.js:623 Uncaught (in promise) Error: PULL DONE failed on /sdcard/Pictures/1642089797468.jpg

getting this, while running your test.
that's
if (decode_cmd(cmd) != "DONE" || zero != 0)
this string ^
so it loads some, then fails.
what I actually want is retrieving a screenshot, so any advises are welcome
my scenario is close to rdp, so I want something like scrcpy, only with pure javascript
