Internal error encountered | DATA_FETCHING_EXCEPTION | Vertex AI Language, Tune a model

I have been trying to tune a model for a week now using the Vertex AI - Language, Tune a model following this tutorial.

• I have used the the sample JSONL as mentioned in the link:

{"input_text": "question: How many people live in Beijing? context: With over 21 million residents, Beijing is the world's most populous national capital city and is China's second largest city after Shanghai. It is located in Northern China, and is governed as a municipality under the direct administration of the State Council with 16 urban, suburban, and rural districts.[14] Beijing is mostly surrounded by Hebei Province with the exception of neighboring Tianjin to the southeast; together, the three divisions form the Jingjinji megalopolis and the national capital region of China.", "output_text": "over 21 million people"}
{"input_text": "question: How many parishes are there in Louisiana? context: The U.S. state of Louisiana is divided into 64 parishes (French: paroisses) in the same manner that 48 other states of the United States are divided into counties, and Alaska is divided into boroughs.", "output_text": "64"}

• Every time I click the "START TUNING" button, I get the message "Internal error encountered", on inspecting the chrome response of the ajax call I see this but have no clue how to resolve it.

• I am not sure if I am doing some mistake or if Vertex AI service is not functional yet?
