EthereumFlow creates a truncated file for a large contract

[OlegMazurov]

When deploying a large contract using EthereumFlow() I get INVALID_FILE_ID. The file uploaded to the network is always truncated at 4096 bytes. The same contract can be successfully deployed using ContractCreateFlow (the file size is 27034 before it is deleted).

I haven't done contract create via ethereum transaction before. Can you share how you build the ethereumData bytes?
Also looking at the code, if the size is bigger than 4096, we do FileAppendTransaction.

The problem is with EthereumFlow.createFile()/createFileAsync(). FileCreateTransaction does not call setKeys() and thus creates an immutable file. An attempt to call FileAppendTransaction() fails with UNAUTHORIZED but the error goes unnoticed as no receipt is requested and fileId is returned representing a truncated file.

I see, I will add the missing keys setter.
Today I tried creating a contract but it failed with INVALID_ACCOUNT_ID. I followed a test we have in EthereumTransactionIntegrationTest.java where we do contract execute, but I could not make it work for contract creation.
I am curious how you are building the RLP data bytes.
