Some ETH->NEAR transfers cannot be finished

Here's the finalisation transaction of the transfer with bridge-testing repo script:

When executed from the frontend, this transaction would have failed before the user is redirected to NEAR Wallet. This is the same issue encountered on Ropsten previously where the computed receipts trie is invalid: the computed trie root does not match the receiptsRoot from the block header. https://github.com/aurora-is-near/rainbow-bridge-client/pull/22 This was reproduced with the ethereumjs tree and with the new lite version we are using.

Ideas why this could be happening:

• Invalid rlp serialization of a receipt (invalid value put in the trie)
• Trie not computed correctly

It seems to be related with: https://github.com/aurora-is-near/rainbow-bridge/issues/557

I'm investigating right now.

Found the problem, and added a patch: https://github.com/near/eth-object/pull/1

For the moment I used the new code to finalise this tx successfully: https://explorer.near.org/transactions/5T6gJfwucQZdDcpy2Tj1Th5bfJ9t3rCjM5UpRK9wfL4n
