High Level Overview of Change

Checking if account is well-formed currently happens before the check if asset , asset2 and amm_account are supplied, which results in an unexpected error messages if any of the fields is malformed. Swap the order of checks, so validity of fields is verified first. Since this is a breaking change, retain the existing behaviour if (apiVersion < 3) and add identical check, but after checks of assets and accounts, if (apiVersion >= 3). Also add unit tests to demonstrate the old and new behaviour.

Type of Change

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Refactor (non-breaking change that only restructures code)
  • Performance (increase or change in throughput and/or latency)
  • Tests (you added tests for code that already exists, or your new feature included in this PR)
  • Documentation update
  • Chore (no impact to binary, e.g. .gitignore, formatting, dropping support for older tooling)
  • Release

API Impact

  • Public API: New feature (new methods and/or new fields)
  • Public API: Breaking change (in general, breaking changes should only impact the next api_version)
  • libxrpl change (any change that may affect libxrpl or dependents of libxrpl)
  • Peer protocol change (must be backward compatible or bump the peer protocol version)

Before: sending an invalid account or asset to amm_info RPC method while other parameters are not set as expected would result in rpcINVALID_PARAMS error. This behaviour is retained in API version 2

After: sending an invalid account or asset to amm_info RPC method while other parameters are not set as expected will result in rpcISSUE_MALFORMED or rpcACT_MALFORMED error. This behaviour is new in API version 3

This resolves XRPLF/clio#1157

this is good to merge - note it preserves the current behaviour in API version 2 and adds a test for it.
