What command(s) is the bug in?

cast keccak

Operating System

Linux

Describe the bug

Git clone my safe-tx-hashes-util. Then run:

./safe_hashes.sh --network zksync --address 0x9fb5F754f5222449F98b904a34494cB21AADFdf8 --nonce 12

It will print:

./safe_hashes.sh: line 517: /home/pcaversaccio/.foundry/bin/cast: Argument list too long

Error: Could not ABI encode the function and arguments. Did you pass in the right types?
Error
parser error:

^
expected hex digits or the `0x` prefix for an empty hex string

The line that throws is here:

local data_hashed=$(cast keccak "$data")

The data that is hashed is very long, so I assume there is some cast keccak size limit issue here: data.txt.

Hmm, I was unable to reproduce this on latest nightly by running the script using:

bash ./safe_hashes.sh --network zksync --address 0x9fb5F754f5222449F98b904a34494cB21AADFdf8 --nonce 12

I also downloaded data.txt and tested it in isolation

cast keccak $(cat data.txt)

cast keccak 0x..

Terminal does lag a bit..but seems to work.

Moreover, the error message displayed is not emitted by the cast keccak, it is emitted by the cast abi-encode cmd here: https://github.com/pcaversaccio/safe-tx-hashes-util/blob/36109aaeb0c376a9ca8ac9464f136fff5371c6ee/safe_hashes.sh#L527
