CF10 - returntype JSON HTTPS - Input length must be multiple of 16 when decrypting with padded cipher

I have a ColdFusion service that doing basic authentication using SQL and returning a structure as JSON

The structure has one element AUTHENTICATED = true . The JSON looks like below

{

  "AUTHENTICATED": true

}

The service works just fine when using HTTP but when using HTTPS I get this error  .

An error occurred while trying to encrypt or decrypt your input string: Input length must be multiple of 16 when decrypting with padded cipher.
