    state_test(env=env, pre=pre2, post=post, tx=tx)

fails with:
"error": "Failed transaction: InvalidBlock()"

if I put chainid = 0 it fails with this error. although it should generate test with any chain id no?

There's no support (I think) in t8n at the moment for multiple chain IDs.

If there was, I don't think we should infer the environment's chain id from the transaction.

So, at the very least, along with the chain_id=0x0 in the transaction, there should be a chain_id=0x0 specified for the execution context somewhere, and this value should be passed to t8n for it configure itself to a different chain id and to accept txs with chain ID != 1.

Also the value should end up in the FixtureConfig after filling the test.
