EOF error when loading data for Vertex Search and Conversation

[testingtechno]

I'm getting an EOF error when creating a data store for my Vertex AI Search and Conversation app. I create the bucket, and upload about 90 JSON files. Then I create a data store under the Vertex AI Search and Conversation, but they all error out because it runs into a EOF error. When I check the logs, it just says incorrect json format. However, the format is correct. I've checked it against Notepad++ JSON extension.
