Wallet Playground需要怎么配置吗，我一直运行失败！

报错信息：

Wallet Playground@0.36.55 start failed for Wallet Playground: Run [Wallet Playground - pre-start] failed: Application account not declared on chain ocap-playground pre-start error GraphQLError: Insufficient fund to pay for tx cost from zNKbVz4cinVsynV9vzULKhhJopWEVZHAq4MP, expected 1.0021678, got 0

环境变量我用的默认值

请各位大佬不吝赐教！🧡🧡
