Stream Enrich Error Deserializing Raw Event

Hello,I am trying to use stream collector(Stdout), Stream enrichment(Stdin) and postgres for storage in Local Server.
I run my collector using:
java -jar stdout/target/scala-2.12/snowplow-stream-collector-stdout-1.0.1.jar --config my.conf

And when i try to run my stream-enrich using below:
java -jar stdin/target/scala-2.12/snowplow-stream-enrich-stdin-1.1.0.jar --config my.conf --resolver file:resolver.json --enrichments file:/home/lal/Desktop/Projects/Zanui/Test/snowplow/3-enrich/config/enrichments/ >> stream_enrich_log_file.txt 2>&1

I get error as given below:
[main] WARN com.networknt.schema.JsonMetaSchema - Unknown keyword exclusiveMinimum - you should define your own Meta Schema. If the keyword is irrelevant for validation, just use a NonValidationKeyword

An error occured: Attempt to download s3://snowplow-hosted-assets/third-party/ua-parser/regexes-latest.yaml to ./ua-parser-rules.yml failed: No AWS credentials provided

Can anyone suggest me what is the issue? If the issue is with Collector setup, where can i see the logs of collector? Thank You
