Examples

1. Opening a JSON file from S3

2. Opening a JSON file from an uploaded file

This example opens a JSON file that was uploaded by the user to Kognitos.

3. Reading a JSON file from S3

This example reads a JSON file stored at the specified S3 URL and returns the parsed JSON object. This is an alternative syntax to "open a json at a file" and provides the same functionality.

the file is "s3://my-bucket/data/json.json"
read the json from the file

4. Reading a JSON file from an uploaded resource

This example demonstrates reading a JSON file containing student and course information from a test resource. The result would be a JSON object with nested structures for student details and course arrays.

the file is "s3://bucket-name/resources/example.json"
read the json from the file

5. Error handling for invalid JSON files

This example shows the error handling when attempting to read an invalid or non-existent JSON file. The system will prompt with "Could not read a json from a file."

the invalid file is "some-file"
read the json from the invalid file
