Stellar cross currency transaction doesn't work - json

Question

I'm unable to execute payment transaction in Stellar testnet.
Initially i use find_path:
curl -X POST https://test.stellar.org:9002 -d '
{
"method": "static_path_find",
"params": [
{
"source_account": "g4e5v2ERpKvdBZrchn6DrWUtvezkXsu5wo",
"destination_account": "gJ3e65GzqERgeeS5oXsv8NGfdZWzm93ej6",
"source_currencies" : [ { "currency" : "SGD", "issuer" : "gDfapfG5hDHuYkbVpugtupkGYVTKXwd59r"} ],
"destination_amount": {
"currency": "MYR",
"value": "1",
"issuer": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS"
}
}
]
}'
The result I get:
{
"result": {
"alternatives": [
{
"paths_computed": [
[
{
"currency": "MYR",
"issuer": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS",
"type": 48
},
{
"account": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS",
"type": 1
}
]
],
"source_amount": {
"currency": "SGD",
"issuer": "gDfapfG5hDHuYkbVpugtupkGYVTKXwd59r",
"value": "0.375"
}
}
],
"destination_account": "gJ3e65GzqERgeeS5oXsv8NGfdZWzm93ej6",
"destination_currencies": [
"MYR",
"STR"
],
"status": "success"
}
}
Then I trying to broadcast transaction in the network:
curl -X POST https://test.stellar.org:9002 -d '
{
"method": "submit",
"params": [
{
"secret": "sfk7dUd4N8cxVFVowsZL4DQgonNP9k8WFBgaV2NmwEQKGzWuqXT",
"tx_json": {
"TransactionType": "Payment",
"Account": "g4e5v2ERpKvdBZrchn6DrWUtvezkXsu5wo",
"Destination": "gJ3e65GzqERgeeS5oXsv8NGfdZWzm93ej6",
"Amount": {
"currency": "MYR",
"value": "1",
"issuer": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS"
},
"Paths": [
[
{
"currency": "MYR",
"issuer": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS",
"type": 48
},
{
"account": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS",
"type": 1
}
]
]
}
}
]
}'
And finally I'm getting unsuccessful result when transaction passed through consensus:

},
"type": "transaction",
"validated": true
}
Why? What I did wrong? I really can't understand...

Answer 1

Anyway I found the problem.
I forgot to add required SendMax parameter when submitting transaction.
curl -X POST https://test.stellar.org:9002 -d '
{
"method": "submit",
"params": [
{
"secret": "sfk7dUd4N8cxVFVowsZL4DQgonNP9k8WFBgaV2NmwEQKGzWuqXT",
"tx_json": {
"TransactionType": "Payment",
"Account": "g4e5v2ERpKvdBZrchn6DrWUtvezkXsu5wo",
"Destination": "gJ3e65GzqERgeeS5oXsv8NGfdZWzm93ej6",
"Amount": {
"currency": "MYR",
"value": "1",
"issuer": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS"
},
"Paths": [
[
{
"currency": "MYR",
"issuer": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS",
"type": 48
},
{
"account": "gsQuUKcxM68nEX9tKR71UH5hZXwrvT2mpS",
"type": 1
}
]
],
"SendMax" : { "currency" : "SGD", "value" : "0.375", "issuer": "gDfapfG5hDHuYkbVpugtupkGYVTKXwd59r" }
}
}
]
}'
