Data Masking in API Gateway Management

API Gateway 10.15

Detailed explanation of the problem:

Data Masking for nested JSON data.
Data Masking works on masking the whole field username to all masked value. However, to mask the username to #ample1, and #ample2, the system return sample1,sample2 as the result. How do we proceed with this as there is no error nor log within tracer funciton.

Sample Data


tried to specify within data masking policy $.accounts.*.username[0] to mask the first character of the username however masking is not done. showing the original data.
