Description

erlang-client doesn't handle body when path include variable.

openapi-generator version

upu_ack(Ctx, Supi, Optional) ->
    _OptionalParams = maps:get(params, Optional, #{}),
    Cfg = maps:get(cfg, Optional, application:get_env(kuberl, config, #{})),

    Method = put,
    Path = ["/", Supi, "/am-data/upu-ack"],
    QS = [],
    Headers = [],
    Body1 = Ts29503NudmSDMClientAcknowledgeInfo,
    ContentTypeHeader = ts29503_Nudm_SDM_client_utils:select_header_content_type([<<"application/json">>]),
    Opts = maps:get(hackney_opts, Optional, []),

    ts29503_Nudm_SDM_client_utils:request(Ctx, Method, [?BASE_URL, Path], QS, ContentTypeHeader++Headers, Body1, Opts, Cfg).

should be:
upu_ack(Ctx, Supi, Ts29503NudmSDMClientAcknowledgeInfo Optional) ->

upu_ack(Ctx, Supi, Ts29503NudmSDMClientAcknowledgeInfo Optional) ->

Use the linked TS29503_Nudm_SDM.yaml declaration to reproduce the erlang-client output for upu_ack/3. Inspect how the generated function signature and request body are assembled when the path contains Supi; done means the generated function represents the body input and passes it correctly to the request helper.
