Config entry {config_entry_id} not found

Error message

Config entry {config_entry_id} not found

What it means

InvalidConfigEntryID raised by config_entry_id_to_source: hass.config_entries.async_get_entry(config_entry_id) returned nothing, so the passed id does not correspond to any existing config entry (deleted, never existed, or typo'd). The function exists to turn a Bluetooth config entry id into a scanner source address.

Solutions

1. Re-fetch the current config entry id (Settings > Devices & Services, or config_entries API) and pass that
2. If the entry was deleted intentionally, remove the automation/script/UI element that still stores the old id
3. Catch InvalidConfigEntryID and re-enumerate entries instead of retrying the same id

Example fix

# before
source = config_entry_id_to_source(hass, stale_entry_id)

# after
entry = hass.config_entries.async_entries(bluetooth.__dict__['DOMAIN'])[0]
source = config_entry_id_to_source(hass, entry.entry_id)

def config_entry_exists(hass, config_entry_id: str) -> bool:
    return hass.config_entries.async_get_entry(config_entry_id) is not None

from homeassistant.components.bluetooth.util import InvalidConfigEntryID
try:
    source = config_entry_id_to_source(hass, entry_id)
except InvalidConfigEntryID:
    entry_id = hass.config_entries.async_entries("bluetooth")[0].entry_id  # re-resolve
    source = config_entry_id_to_source(hass, entry_id)

When it happens

Trigger: Calling config_entry_id_to_source (directly or via a websocket/API that accepts a config_entry_id) with an id from a stale UI session after the entry was removed, a truncated id, or a random string.

Common situations: Frontend dialog holding an entry id across a reload/delete; scripts or blueprints referencing an entry that was re-created with a new id; copy-paste of an id with missing characters.
