CPLB error when calling adi_gpio_RegisterCallback()

I am calling following adi function in CCES 2.10.0 for a BF706 project.

adi_gpio_RegisterCallback(ADI_GPIO_PIN_INTERRUPT_2, ADI_GPIO_PIN_5,Handler_drdy, (void*)0);

and when running it breaks with following error at highlighted line 536.

A non-recoverable error or exception has occurred.
Description: a data COLB miss has occurred without a corresponding CPLB entry.
General Type: RunTimeError
Specific Type: DCPLBMissWithoutReplacement

I checked/unchecked CPL box in  startup config and both lead to same break above. What's going on?
