message Failed transaction: is not sufficient enough to match exception code

the exception string is empty in line
src/ethereum_spec_tools/evm_tools/t8n/init.py

this probably goes to EELS repo
ethereum/execution-spec-tests#881

command:

uv run fill "tests/cancun/eip4844_blobs/test_blob_txs.py::test_insufficient_balance_blob_tx[fork_Cancun-blockchain_test--exact_balance_minus_1-tx_max_fee_per_blob_gas_1-no_calldata-tx_value_1-tx_max_priority_fee_per_gas_0-tx_max_fee_per_gas_7-no_access_list]"

Note to Implementer

Once all the specific exception types are being thrown correctly, make sure to update the test loader to take advantage:

execution-specs/tests/helpers/load_state_tests.py

Lines 72 to 74 in 420f7a8

	# TODO: Once all the specific exception types are thrown,
	# only `pytest.raises` the correct exception type instead of
	# all of them.
