    Hello Harini,

     

    The error you are encountering indicates that your code is trying to perform an operation on an object reference that has not been initialized (i.e., it is null). The issue may have occurred due to the following reasons:

     

    1) Uninitialized Object: Ensure that all objects are properly initialized before use. For example:

    Verify that your S3 client is correctly initialized. Check that the bucket name and file key are correctly specified and not null.

     

    2)Incorrect AWS Credentials or Configuration: Make sure your AWS credentials and configurations are correct. Invalid credentials can result in NullPointerException.

     

    3)File Existence and Permissions: Ensure that the file you are trying to access exists in the specified S3 bucket and has the necessary permissions to read the file.

     

    Thanks,

    Akshay.
