Sorry for this basic question, I couldnt build the app,

Error :
“message”: “Binding to non-existent server app ‘mqttClientApi’.”,

.cdef file
api:
{
modemServices/le_mrc.api
modemServices/le_mdc.api
modemServices/le_sim.api
modemServices/le_info.api
le_data.api
// ${LEGATO_ROOT}/apps/platformServices/mqttClient/mqtt.api
mqttClientApi/mqttClient.api
}

.adef file

bindings:
{
TEXTMqttTLSEXE.TEXTMqttTLS_Component.le_mdc -> modemService.le_mdc
TEXTMqttTLSEXE.TEXTMqttTLS_Component.le_mrc -> modemService.le_mrc
TEXTMqttTLSEXE.TEXTMqttTLS_Component.le_sim -> modemService.le_sim
TEXTMqttTLSEXE.TEXTMqttTLS_Component.le_info -> modemService.le_info
TEXTMqttTLSEXE.TEXTMqttTLS_Component.le_data -> dataConnectionService.le_data
TEXTMqttTLSEXE.TEXTMqttTLS_Component.mqttClient -> mqttClientApi.mqttClient
}
