🐛 Bug

AssertionError: {"message":"parse request payload error: Expected input type "TransactionPayload", found {"type":"script_function_payload","function":"0x1::coin::transfer","type_arguments":["0x1::aptos_coin::AptosCoin"],"arguments":["0xb59102d3ae93f30ac7cb17300b60bbad227dd5f55a10d05ab95b6340921c6737","1000"]}. (occurred while parsing "UserTransactionRequestInner") (occurred while parsing "EncodeSubmissionRequest")","error_code":"web_framework_error","vm_error_code":null}

I followed the linked tutorial "https://aptos.dev/guides/creating-a-signed-transaction" and the program ran "transfer-coin.py", but it didn't output as expected

    # Have Alice give Bob another 1_000 coins using BCS
    txn_hash = rest_client.bcs_transfer(alice, bob.address(), 1_000)
    rest_client.wait_for_transaction(txn_hash)

Officially changed the playload param script_function_payload to entry_function_payload.I think you can check python sdk code about translate function.

[twtesmarry]

thank you for your reply. "python sdk code about translate function", where can I find what you said, can you send me the detailed link or screenshot? Looking forward to your reply, thank you

[gregnazario]

What's the version of the SDK you're using?

[twtesmarry]

0.2.0

[jjleng]

can you please use 0.3.0. it should work

[twtesmarry]

SDK 0.3.0

[twtesmarry]

Does SDK 0.3.0 support Testnet network? If supported, how to modify the parameters of the request?
