Ok yes it's crashing when it tries add it to IPFS. Looking into it. Thanks

Hi again. I kind of figured out where the problem is but wasn't able to reproduce it locally to debug further. Do you happen to have the same issue with...

It seems to be a rare thing and happens with relatively large contracts with many files. It tries to add the metadata file to IPFS before the file was written...

Documenting other contracts that had the same issue (no metadata.json and `ENOENT` file not found crash): ``` - partial_match/4/0x430968AB0fbA6c5097c430A51f59CA35d018B5e0/metadata.json' - partial_match/421611/0xfc9ffA88a07da8AfB2820c0aCA2A0c67f45Ceb17/metadata.json - partial_match/4/0xff7cE5dfb715049ab57Bad08338C5848981210bB/metadata.json - partial_match/4/0x5eF903387Af0fF26215a934D2B21E4204939f619/metadata.json - partial_match/42220/0xC96c78E46169cB854Dc793437A105F46F2435455/metadata.json - partial_match/4/0xD1D32aa94409E59439364de781b6433Cf540706d/metadata.json ```
