Sep24Invalid
Exception thrown when SEP-24 request parameters are invalid (HTTP 400).
Indicates that the anchor rejected the request due to invalid, malformed, or missing parameters. This error typically occurs when:
Asset code is not supported by the anchor
Required fields are missing (e.g., asset_code)
Invalid amount format or value
Invalid account format
Unsupported deposit/withdrawal type
Amount exceeds anchor limits
Missing required KYC information
Recovery actions:
Verify the asset code is supported (check /info endpoint)
Ensure all required parameters are provided
Validate amount is within anchor's min/max limits
Check account ID format is valid
Example - Handle invalid asset:
suspend fun initiateDeposit(
sep24Service: Sep24Service,
assetCode: String,
jwt: String
): Sep24DepositResponse? {
try {
return sep24Service.deposit(assetCode, jwt)
} catch (e: Sep24InvalidRequestException) {
println("Invalid request: ${e.message}")
// Check supported assets
val info = sep24Service.info()
val supportedAssets = info.deposit.keys
println("Supported assets: ${supportedAssets.joinToString()}")
return null
}
}Example - Validate before request:
suspend fun depositWithValidation(
sep24Service: Sep24Service,
assetCode: String,
amount: String?,
jwt: String
): Sep24DepositResponse? {
// Get anchor info for validation
val info = sep24Service.info()
val assetInfo = info.deposit[assetCode]
if (assetInfo == null) {
println("Asset $assetCode not supported for deposit")
return null
}
// Validate amount if provided
if (amount != null) {
val amountValue = amount.toDoubleOrNull()
if (amountValue == null || amountValue <= 0) {
println("Invalid amount: $amount")
return null
}
assetInfo.minAmount?.let { min ->
if (amountValue < min) {
println("Amount below minimum: $min")
return null
}
}
assetInfo.maxAmount?.let { max ->
if (amountValue > max) {
println("Amount above maximum: $max")
return null
}
}
}
try {
return sep24Service.deposit(assetCode, amount, jwt)
} catch (e: Sep24InvalidRequestException) {
println("Request rejected: ${e.message}")
return null
}
