The hashes they generate don't look any different, but using the python module always produces an error

Please. use this URL "https://rpc.ankr.com/eth_goerli" as the URL_TO_ETH_NETWORK
And please have a try with the following example:
https://github.com/zksync-sdk/zksync2-python/blob/master/examples/01_deposit.py

[vyastrebovvareger]

I will investigate your issue as soon as possible

[lusharenck]

请。使用此 URL"https://rpc.ankr.com/eth_goerli"作为 URL_TO_ETH_NETWORK 请尝试以下示例： https: //github.com/zksync-sdk/zksync2-python/blob/master/examples/01_deposit.py

I got the same error after replacing the rpc
0x8a5d3c948e182e8921b8c43fba2d9d1523a5d557b443be7257466f90d74125fd

One thing that come to mi mind that you directly setup l2_gas_limit
and this one

   gas_per_pubdata_byte = None # 800
    gas_limit = None # 118722

I would go step by step. Run test from example. Then if you need to calculate precise l2_gas_limit I investigate it and provide an example

I think the key of this issue is that the value sent on the deposit doesn't add the fee will be used in L2.

here the l1_value should be replaced with value.

zksync2-python/zksync2/provider/eth_provider.py

Lines 182 to 196 in 69348c2

	value = base_cost + operator_tip + l2_value
	check_base_cost(base_cost, value)
	call_data = to_bytes(call_data)
	tx_receipt = self.main_contract.request_l2_transaction(contract_l2=contract_address,
	l2_value=l2_value,
	call_data=call_data,
	l2_gas_limit=l2_gas_limit,
	l2_gas_per_pubdata_byte_limit=gas_per_pubdata_byte,
	factory_deps=factory_deps,
	refund_recipient=refund_recipient,
	gas_price=gas_price,
	gas_limit=gas_limit,
	l1_value=l1_value)

Also, I think here the gas_limit should be l2_gas_limit

zksync2-python/zksync2/provider/eth_provider.py

Lines 179 to 181 in 69348c2

	base_cost = self.get_base_cost(gas_price=gas_price,
	gas_per_pubdata_byte=gas_per_pubdata_byte,
	gas_limit=gas_limit)

Let me know if I'm wrong😄.

Ran into the same issue today with deposits. Started out with error "qp" for the gas per pubdata value not being right (eth provider has this set at 50000). After I overrode that I got the "mv" error and it looks like the SDK is setting the base_cost to 0. Got around that by calculating the base cost with get_base_cost and passing it as the operator tip.

            gas_price = web3.eth.gas_price
            operator_tip = eth_provider.get_base_cost(gas_limit=eth_provider.RECOMMENDED_DEPOSIT_L2_GAS_LIMIT, gas_per_pubdata_byte=800,gas_price=gas_price)
            l1_tx_receipt = eth_provider.deposit(token=Token.create_eth(),
                                    amount=web3.to_wei(str(depositAmount), "ether"),
                                    gas_per_pubdata_byte=800,
                                    operator_tip=operator_tip)

this is the right solution

I encountered the same issue today, this code can help solve it, thank you.
