As the LSP-Lender APIs are async, there are two different places where the error can be thrown. First is as part of the Ack and the second is as part of the Actual Response. The error messages can be classified depending on where they appear

1. Errors captured inside Ack object - Errors captured inside Ack object are at a very basic level. These include errors which can be immediately flagged without having to do a lot of processing
   a. Security Errors - Errors related to signature mismatch
   b. Validation Errors - Errors like missing mandatory attributes, incorrect values passed for an ENUM field etc.
2. Response API Errors - These are the errors captured inside Response node of the actual Response API - Each Response API that hits the LSP has a dedicated object called Response. This object will capture all the API level business errors. For example, if there are errors in CreateLoanApplicationRequest, they will be captured inside the Response object of the CreateLoanApplicationResponse payload. These can be of two types
   a. Business Errors - Errors related to the business logic implemented in each APIs
   b. System Errors - Errors related to the auxiliary systems to which the lender system talks to like AA, Credit Bureaus, PCR etc
