Sbt 如何解决；应为右括号“；config.hocon文件中是否存在异常？

我有一个

config.hocon.sample

文件，它具有以下配置：

        minBackoff = {{enrichStreamsOutMinBackoff}}
        minBackoff = ${?ENRICH_STREAMS_SOURCE_SINK_BACKOFF_POLICY_MIN_BACKOFF}
        maxBackoff = {{enrichStreamsOutMaxBackoff}}
        maxBackoff = ${?ENRICH_STREAMS_SOURCE_SINK_BACKOFF_POLICY_MAX_BACKOFF}

但是，当我尝试通过

sbt

运行代码时，会出现以下错误：

$ sbt "project kinesis" "runMain com.snowplowanalytics.snowplow.enrich.stream.KinesisEnrich --config config/config.hocon.sample --resolver file:config/iglu_resolver.json  --enrichments file:config/enrichments/"
