I am getting error is "peertransfers". Error"Both internal funds transfer account

[muhammadadnanij]

I have integrated the marqata apis. I am doing "peertransfers". Previously it was working fine. Now suddenly it is giving me errors like:
Api Url is: "https://sandbox-api.marqeta.com/v3/peertransfers"
{
"error_message": "Both internal funds transfer accounts must be owned by the same user",
"error_code": "422053"
}
Note: It was working fine.
The body i am providing is:
{
"token": "my_peertransfer_01",
"sender_user_token": "8abab2c5-0914-43f9-aad7-6af2fd78a4aa",
"recipient_user_token": "c3e0e499-94d6-4a34-87f5-ca506a29e4c0",
"currency_code": "USD",
"amount": 50
}

Hi @muhammadadnanij .  That is the correct behavior for peer transfers.  As far as we know, it shouldn't behave any other way.

@reneemq hi, Sorry but previously this api is wroking fine. Now its is giving me this error that i mentioned. How can api is giving some times success response and sometimes Faliure response like i mentioned??
This is error: {
"error_message": "Both internal funds transfer accounts must be owned by the same user",
"error_code": "422053"
}
This is not the correct way. Its should transfer the amount. Previously its sending money but now its not. even though i havent change anything. 
Please email me. I need your help please.
