Sep08InvalidTransactionResponseException

Exception thrown when the approval server returns a malformed or unexpected response to a transaction approval request (postTransaction).

Indicates that the response from the approval server could not be parsed or does not conform to the SEP-8 specification. This typically occurs when:

• The response JSON is malformed or missing required fields

• The response status field contains an unrecognized value

• A "revised" response is missing the required tx field

• A "rejected" response is missing the required error field

• An "action_required" response is missing the required action_url field

• The response HTTP status code is unexpected

Recovery actions:

• Verify the approval server URL is correct

• Check the approval server logs for errors

• Ensure the transaction XDR is well-formed before submission

• Contact the asset issuer if the problem persists

Example - Handle invalid response:

try {
    val response = sep08Service.postTransaction(signedTxXdr)
} catch (e: Sep08InvalidTransactionResponseException) {
    println("Approval server returned invalid response: ${e.message}")
}
