Possible Causes

There are several potential causes for this error:

  • Incorrect Subscript Syntax: Using incorrect syntax when accessing JSON array or object elements can trigger this error. Ensure that you are using the correct subscript syntax, such as using square brackets for arrays and arrows for objects.
  • Nonexistent Subscript: Trying to access a non-existent element within a JSON array or object will result in this error. Double-check that the subscript you are using corresponds to an existing element.
