Troubleshooting Errors
Error Codes
In order to reduce gas usage and code size, /spark-protocol contracts return numbered errors. If you are making calls to the protocol and receive numbered errors, you can use the reference below to know what is the error. Alternatively, you can also find what the numbers represent by checking the Errors.sol.
