Bug Description
my attempts to run /compact in advance of running out of space give an error message ( Error: Error during compaction: Error: Conversation too long. Press esc twice to go up a few messages and try
again.) However if I just keep going down to 0% then auto-compact kicks in and works fine.
NOTE: I also got "Error submitting feedback / bug report" so used to feature to create an issue in GH instead which did work.

i'm also getting this error
auto compact is the only thing working
Same here! After i had just 1% context left, i tried /compact command and it failed. I exited cloude code (ctrl + c -> twice) and then claude --continue and then /compact worked.
This should be fixed! ;)
it's now occuring again after 2.0.21 / 22
