Using the Custom Module in AzureML Designer

Following the steps in the notebook I am able to create a Module and I also can see the module in the AzureML designer (Under Custom module).
https://github.com/Azure/MachineLearningNotebooks/blob/master/how-to-use-azureml/machine-learning-pipelines/intro-to-pipelines/aml-pipelines-how-to-use-modulestep.ipynb

Creating pipeline with ModuleStep and running a pipeline from notebook is also possible. But while trying to use the module in the designer, and trying to run a pipeline in an experiment, getting following error,
**Error**
Can't build command text for [ModelExplainer], moduleId [ed91c7cf-028f-4867-a228-b32f74cb8ff2] executionId [e4436bd8]: Assignment for parameter Target is not specified

Where ModelExplainer is the experiment name.

從 how-to-use-azureml/machine-learning-pipelines/intro-to-pipelines/aml-pipelines-how-to-use-modulestep.ipynb 開始，並在 AzureML Designer 中重現該模組。比較 notebook 建立的模組與 Designer 實驗執行，重點關注報告中缺少的 Target 指派；當 pipeline 能夠在不出現所示命令建置錯誤的情況下執行時，即視為完成。
