Unspecific error thrown by "validation" policy in API Management

Please refer to the ticket: TS001157822 for more information.

I am copying below a message from IBM support team which referred us to open RFE.

Hello Ankit,

I have discussed this with our extended team in detail. I am getting an understanding that this error message is thrown from DataPower and it is working as designed. From your viewpoint I understand that the error message is not specific and may not be helpful. If you think that the error message needs to updated, then the enhancement of this validation error message in the case of additionalProperties with a value of false will require a RFE. You should open using and should specify DataPower as the product.

Please let us know if any related questions. If none, please provide permission to close the

case. Thanks.

with regards

    Thank you for your input. The messages are correct and while understandably not as detailed as your would like we consider the gateway to be primarily a runtime in this case and we would recommend customers utilized development tooling to assist in more detailed debugging.

    IBM API Connect provides terrible error messages in general for the Errors thrown to the Catch block. The Validate policy is the worst with the cryptic JSV001, JSV006 messages that don't provide any detail. Just adding the JSON field property name to the error message would go a long way.

    I would like this case to return being under consideration.

    This error message needs to be updated. I don't understand why I should open a different RFE, because this RFE's product is already "IBM DataPower Gateways".

    By the way, the error is unclear not only in the case of "additionalProperties=false", but in many other cases.

    For example, if there's an enum in the schema, the error for sending a value which is not a part of the enum looks like this: "[JSV0013] Invalid value: the value is not among the permitted enumerated value". Once again, it doesn't state what is the value, what is the enum, what field caused it. If I have several fields which are defined with enums, I have no idea which of those field got an illegal value and what was that value.

    There are many more unclear errors, just like this in terms of JSON validation.
