Connect to a postgres database

[Jon Nance]

I'm trying to connect Legend to an existing postgres database where I'd like to run queries off of. The documentation on the tutorials https://legend.finos.org/docs/tutorials/studio-relational-mapping mainly cover connecting to a H2 database that is created within Legend.

I've attempted to enter the details into "New Connection" within Legend Studio, but keep receiving a 'null pointer exception'. Additionally in the 'store' tab, I see that it's highlighted in red, though I'm not sure what it means

How should I go about making this connection?

Thanks

You need to have a store associated with your connection.
You can either begin with a connection and create your store using the build database feature or begin with a store and add the connection later. The error comes from the fact that you have no associated store.
We are in the middle of revamping the studio documentation but for now here is a detailed description of how to add this using both methods.
docs for adding store/connection
Let me know if you have any questions based on the two videos.
