Description

https:dashboard error

with version 3.0.1 it works fine.
with version 3.1.x and 3.2.x if I enable https on the dashbord plugin configuration I get this error.

[error] [Plugins] Load plugin emqx_dashboard failed, cannot start plugin emqx_dashboard for {bad_return,
{{emqx_dashboard_app,
start,
[normal,
[]]},
{'EXIT',
{{badmatch,
{error,

[{minirest,
start_https,

[{file,
"/emqx_temp/emqx_rel/_checkouts/minirest/src/minirest.erl"},
{line,

{lists,

"lists.erl"},
{line,

{emqx_dashboard_app,
start,

[{file,

{line,
28}]},
{application_master,
start_it_old,

[{file,
"application_master.erl"},

What has changed compared to previous versions?

I guess options is missing in emqx_dashboard:
.....
minirest:start_https(listener_name(Proto), ranch_opts(Port, Options), Dispatch).

ranch_opts(Port, Options) ->
NumAcceptors = get_value(num_acceptors, Options, 4),
MaxConnections = get_value(max_connections, Options, 512),
#{num_acceptors => NumAcceptors,
max_connections => MaxConnections,
socket_opts => [{port, Port}]}. <- should be: socket_opts => [{port, Port}|Options]}

better:

ranch_opts(Port, Options0) ->
NumAcceptors = get_value(num_acceptors, Options0, 4),
MaxConnections = get_value(max_connections, Options0, 512),
Options = lists:foldl(fun({K, _V}, Acc) when K =:= max_connections orelse K =:= num_acceptors->
Acc;
({K, V}, Acc)->
[{K, V} | Acc]
end, [], Options0),

Res = #{num_acceptors => NumAcceptors,
max_connections => MaxConnections,
socket_opts => [{port, Port} | Options]},
Res.
