Resolution resolution

2 checks are being done to validate an ECID during ingestion

It should be 38 characters long
Split the 38 chars string into substrings (19 chars each); these substrings should be valid java Long (i.e, max value of 263-1)

In this case 1) is confirmed as 38 characters long however b) the second half of substring “932344476478431511” it too big causing the error to occur
