Redshift Data API Fetching Records

I am using Redshift Data API to fetch the records from redshift. If the timeout is not mentioned manually the query is not returning records. The error thrown is com.amazon.npcmanagementservice.component.ProcessClaimReportComponent:243: UnKnown Exception occurred during processing the excel file. Reason : Query does not have result. Please check query status with DescribeStatement. (Service: RedshiftData, Status Code: 400, Request ID: afd1c802-e2c5-4e72-93b6-39a96bdb18f7) software.amazon.awssdk.services.redshiftdata.model.ResourceNotFoundException: Query does not have result.

If incase timeouts are to be mentioned what are the default values?

According to this https://docs.aws.amazon.com/redshift/latest/mgmt/data-api.html#data-api-calling-considerations-parameters it says SqlParameters can't be null. But in my case I wanted the null values to be substituted in the query. Is there any possible way to do this?
