Session goal objective must contain 1..={MAX_SESSION_GOAL_OB

Error message

Session goal objective must contain 1..={MAX_SESSION_GOAL_OBJECTIVE_CHARS} characters

What it means

Validation in SessionGoalState::validate: the trimmed objective length fell outside the 1..=MAX_SESSION_GOAL_OBJECTIVE_CHARS (8192) bound. Goal objectives are persisted as bounded files (MAX_SESSION_GOAL_FILE_BYTES 64 KiB) and an empty or oversized objective is invalid data for the goal schema.
