ChallengeValidationErrorInvalidSourceAccount class

Validation error thrown when an operation has an invalid source account.

According to SEP-10, challenge transactions have strict requirements for operation source accounts:

First operation:

• Source account must match the client's account ID that requested the challenge
• This proves the challenge is intended for the specific client

Subsequent operations:

• For "client_domain" operations: source must be the client domain's account ID
• For other operations: source must be the server's signing key account ID
• All operations must have a source account set (not null)

Invalid source accounts indicate:

• Challenge was generated incorrectly by the server
• Transaction has been tampered with
• Challenge is intended for a different account

This validation prevents attacks where a challenge for one account is used to authenticate a different account.

Example handling:

try {
  webAuth.validateChallenge(challenge, accountId, clientDomainId);
} on ChallengeValidationErrorInvalidSourceAccount catch (e) {
  print('Invalid source account in challenge operations');
  // Do not sign this challenge
}
