Bug ID 1351493: Invalid JSON node type while support-introspection enabled

Last Modified: May 29, 2024

Affected Product(s):
BIG-IP APM(all modules)

Known Affected Versions:
16.1.0, 16.1.1, 16.1.2,,, 16.1.3,,,,,, 16.1.4,,,

Opened: Sep 13, 2023

Severity: 4-Minor


As per RFC 7519, the expected value “exp” in the JWT token is a numerical value. JSON itself does not have a native type for integers, so all numerical values are represented as either numbers (without quotes) or strings (with quotes). In our case, we throw an exception if it is not a number to consider the string value. We also have an additional check to ensure it is a valid type.


Support-introspection cannot be enabled.


The issue occurs only when support-introspection is enabled.


Disable support-introspection.
