Fix JSONDecodeError

in Pydantic Settings

Solution

JSONDecodeError in pydantic-settings often arises when environment variables expected to contain JSON (like secrets) are improperly formatted or contain invalid JSON syntax. To fix this, ensure the environment variable holds a valid JSON string; use a JSON validator tool before setting the variable or consider encoding the data differently if strict JSON format is not necessary. Verify the variable's value and type using `os.environ.get()` before pydantic tries to parse it.
