How to get last activity of user from ejabberd?

问题

I try to get the last_activity of user using ejabberd API get_last but getting this error: REST API Error: get_last([{<<"user">>,<<"67456efc-be57-4cbd-a176-527de2dce19d@faiqkhan-virtualbox">>},{<<"host">>,<<"faiqkhan-VirtualBox">>}]) -> error:{module_not_loaded,mod_last,<<"faiqkhan-VirtualBox">>} [{gen_mod,get_module_opts,2,[{file,"src/gen_mod.erl"},{line,338}]},{gen_mod,get_module_opt,3,[{file,"src/gen_mod.erl"},{line,318}]},{gen_mod,db_mod,3,[{file,"src/gen_mod.erl"},{line,352}]},{mod_last,get_last,2,[{file,"src/mod_last.erl"},{line,181}]},{mod_last,get_last_info,2,[{file,"src/mod_last.erl"},{line,248}]},{mod_admin_extra,get_last,2,[{file,"src/mod_admin_extra.erl"},{line,1382}]},{mod_http_api,handle2,4,[{file,"src/mod_http_api.erl"},{line,268}]},{mod_http_api,handle,4,[{file,"src/mod_http_api.erl"},{line,229}]}] I checked my ejabberd.yml mod_last: {} is added in the modules tag.

Check the documentation of the get_last API call you want to use. It seems you are not providing the correct arguments: https://docs.ejabberd.im/developer/ejabberd-api/admin-api/#get-last
