Keep KV on idle unload must be true or false.

Error message

Keep KV on idle unload must be true or false.

What it means

Raised by set_openai_auto_switch in openai_auto_switch_settings.py:315-317 when keep_kv is provided and _coerce_bool returns None. Accepted: real bools and strings 1/true/yes/on, 0/false/no/off (case-insensitive). Integers 1/0 and any other token ("keep", "y", "checked") are rejected.

Solutions

1. Pass a real bool (keep_kv=True)
2. Normalize checkbox ints to bool: bool(int(raw)) before calling
3. Whitelist the coercion tokens in your validation layer
4. Omit the argument to leave the stored setting unchanged

Example fix

# before
set_openai_auto_switch(enabled=True, keep_kv=1)

# after
set_openai_auto_switch(enabled=True, keep_kv=True)

When it happens

Trigger: set_openai_auto_switch(enabled=True, keep_kv=1) from a checkbox that yields ints; keep_kv="keep"; keep_kv=[True]. Python None is allowed (leave stored value).

Common situations: HTML checkbox handlers sending "1"/"0" as ints after JSON parsing; API clients normalizing booleans to ints; truthy strings from environment variables like "yes please".
