Couldn't find network parameters file and compatibility zone wasn't configured/isn't reachable, corda - postgresql

Question

Am stuck, trying to integrate azure postgres with corda. I'm using gradle's deployNodes task to create the network locally.
Below is the exception that I get.
[ERROR] 2021-09-06T06:53:02,290Z [main] internal.NodeStartupLogging. - Exception during node startup: Couldn't find network parameters file and compatibility zone wasn't configured/isn't reachable. - Couldn't find network parameters file and compatibility zone wasn't configured/isn't reachable. [errorCode=1917kd6, moreInformationAt=https://errors.corda.net/OS/4.5/1917kd6]
I had no issues when connected with a local instance of postgres installed on my machine.
Below given is the azure postgres configuration that errors.
extraConfig = [
'dataSourceProperties' : [
'dataSourceClassName': 'org.postgresql.ds.PGSimpleDataSource',
'dataSource.url': 'jdbc:postgresql://azure_database_name.postgres.database.azure.com:5432/demo?searchpath=demo_schema?ssl=true',
'dataSource.user': 'userN#me#azure_database_name',
'dataSource.password': 'pa$$word'
]

Answer 1

Try to do this:
create a /drivers folder in your project root folder. This folder will contain the postgresql-XX.X.jar of PostgreSQL
update your build.gradle to add the location of the jar of the drivers with jarDirs, like so:
extraConfig = [
jarDirs : ['/your-project-absolute-path/drivers'],
dataSourceProperties : [
'dataSourceClassName': 'org.postgresql.ds.PGSimpleDataSource',
'dataSource.url': 'jdbc:postgresql://azure_database_name.postgres.database.azure.com:5432/demo?searchpath=demo_schema?ssl=true',
'dataSource.user': 'userN#me#azure_database_name',
'dataSource.password': 'pa$$word'
]
]
run ./gradlew deployNodes
run ./build/nodes/runnodes
the node should start (it will take some time since it has to connect to Azure DB)
