fails with

=ERROR REPORT==== 23-Dec-2024::20:03:27.110621 ===
Error in process <0.69.0> with exit value:
{badarg,[{erlang,element,[1,foo],[{error_info,#{module => erl_erts_errors}}]},
         {group,type,1,[{file,"group.erl"},{line,1281}]},
         {group,log_io_request,3,[{file,"group.erl"},{line,1271}]},
         {group,io_request,6,[{file,"group.erl"},{line,227}]},
         {group,server_loop,3,[{file,"group.erl"},{line,153}]}]}
