hi ,
I’m new in kong and try to make a POC to manage our legacy API
I’m blocked when i try to load a customer after service response
i try to use load_consumer in body_filter or header filter. but this line failed.
local consumer, err = kong.client.load_consumer("25bed290-2458-4c50-9d53-6f58e0e7aea4")
this is results for some phases (access, header filter, body_filter ):
access : ok customer loaded
header_filter : API disabled in the context of header_filter_by_lua

On kong github i find this. it seems to be possible to use load_consumer in header_filter or body_filter
-- Returns the consumer from the datastore (or cache).
-- Will look up the consumer by id, and optionally will do a second search by name.
-- at function kong.client.load_consumer
-- at phases access, header_filter, body_filter, log
-- at tparam string consumer_id The consumer id to look up.
-- at tparam [opt] search_by_username boolean. If truthy,
-- then if the consumer was not found by id,
-- then a second search by username will be performed
-- at treturn table|nil consumer entity or nil
-- at treturn nil|err nil if success, or error message if failure
-- at usage
-- local consumer_id = "john_doe"
-- local consumer = kong.client.load_consumer(consumer_id, true)
function _CLIENT.load_consumer(consumer_id, search_by_username)
check_phase(AUTH_AND_LATER)
....
Do you see where could be my mistake ?
thanks
