session interrupt failed

[yongyong123]

In Claude Agent SDK, manual user pause is flaky. Most sessions stop successfully, but in some cases instance.interrupt() does not reach the expected completion path (missing interrupt() completed log), and the session appears not to pause reliably. Could you clarify the timing/state requirements for interrupt() and whether this intermittent behavior is a known issue?
