@Paasmer Sorry for the delay getting back to you. Your error originates in a section of code that reads a contract artifact stored as a JSON object in the folder build/contracts. For some reason that file is getting corrupted but it's not clear why.

• Could you open the file that fails, look at position 15566 in a text editor (the character should be a colon) and report back what's there?
• Are you able to migrate using ganache-cli?
• Is there anything unusual about the way you're building your project? Any additional information you can provide might be helpful here.

Thanks.

@Paasmer I'm going to close for house-keeping since it's been a few days and it seems like you might have resolved this on your own? If not please re-open - will continue to watch this issue in case anyone else starts seeing the error. Thanks for reporting!
