Convert to Currency ID Failed

[twpony]

I have tried this project in my localhost docker. My endpoint: wss://karura.api.onfinality.io/public-ws. And I set StartBlock: 500000 in project.yaml. I use the latest version of @subquery/types(the original version "^0.8.5" in this package.json will throw error, so i changed the latest version setting). Other settings is the same as the project. But I get the [Convert to Currency ID] Error as follows, and the error seems to happen at block 500025.
