What causes the Invalid Json message due to spacing problem?

edit

The Invalid JSON message is typically caused by a spacing problem when the JSON data is not properly formatted. JSON requires specific syntax and spacing, and even a single misplaced character or missing bracket can cause an error. This can be caused by human error, such as typos or accidentally adding extra spaces, or system errors, such as corrupt data or outdated software. To avoid this error, it is important to ensure that the JSON data is properly formatted and that the software used to parse the data is up to date.
