import json

def task_func(utc_datetime, salt='salt', password_length=10, seed=0):
    """
    Generate a random lowercase alphanumeric password of length password_length
    and then encrypt it as a JSON string. The password is hashed using SHA-256.
    The hashing uses the combination of the user provided salt and the complete 
    conventional string representation of the user provided UTC datetime. 
    
    Parameters:
    utc_datetime (datetime): The datetime in UTC.
    salt (str, optional): The salt to be used for hashing the password. Defaults to 'salt'.
    password_length (int, optional): The length of the password to be generated. Defaults to 10.
    seed (int, optional): The seed for the random number generator. Defaults to 0.
    
    Returns:
    str: The hashed password encoded as a JSON string.
    
    Requirements:
    - json
    - datetime
    - random
    - hashlib

    Raises:
    - ValueError: If the utc_datetime is not a datetime object or the salt is not a string.
    
    Example:
    >>> utc_time = datetime(2023, 6, 15, 12, 0, 0, tzinfo=pytz.UTC)
    >>> password_json_str = task_func(utc_time)

instruct prompt

Generate a random lowercase alphanumeric password of length password_length and then encrypt it as a JSON string. The password is hashed using SHA-256. The hashing uses the combination of the user provided salt and the complete conventional string representation of the user provided UTC datetime.
The function should raise the exception for: ValueError: If the utc_datetime is not a datetime object or the salt is not a string.
The function should output with:
    str: The hashed password encoded as a JSON string.
You should write self-contained code starting with:
