Opensearch vector store bugs

[tstephen1]

Following the walkthrough in spring ai documenation for opensearch vector store on aws, the following properties are incorrectly located:

spring.opensearch.aws.host
spring.opensearch.aws.service-name
spring.opensearch.aws.access-key
spring.opensearch.aws.secret-key
spring.opensearch.aws.region

these only work if located on
spring.ai.vectorstore.opensearch.*

else causes error:
Caused by: java.lang.NullPointerException: Access key ID cannot be blank.

Also similarity search for index with the following json mapping gives:
Similarity search results with error:
org.opensearch.client.opensearch._types.OpenSearchException: Request failed: [search_phase_execution_exception] all shards failed

for mapping json:
mappingJson: |
"properties": {
"embedding": {
"type": "knn_vector",
"dimension": 1536
}
}

I had exactly the same issue. I fixed it by disabling the json indentation in Jackson ObjectMapper.

I tried this but it didnt work -

spring:
jackson:
serialization:
indent_output: false

Could you give an example?
