JSON Web Token (JWT) Parser

Reshma,

It is because the iRule has ACCESS commands in it that cannot function without an access profile assigned. The ACCESS commands are there to assign the JWT values into APM session variables.

To resolve this problem you must follow the directions provided by the error message and assign an access profile (enabled by licensing and provisioning APM) onto the virtual server before you can assign this iRule.

It is possible to comment out any ACCESS commands from this iRule and use in LTM only as an alternative. However, as noted at the top and by Walter, this does not verify the signature of the JWT and may have performance problems at large scale. The built-in JWT parsing functionality in APM is highly recommended to be used instead and is the supported method of doing this.
