Finding this problem is not easy. I will give the running environment later.

We can reproduce this bug by following the steps:

git clone git@github.com:taikoxyz/taiko-client.git
cd taiko-client

# use eip4844_bug_environment branch
git checkout eip4844_bug_environment

# start docker compose
./internal/docker/start.sh

# run test case.
cd pkg/solidity
go test -v -run TestBlob

We used the FillTransaction API at this line.
The test case(TestBlob) shows that if opts.GasLimit == 0 will run this line and then appear error otherwise run succeed.

@s1na The test environment is ready to reproduce. Thanks for verifying!
