Problem
The filters input parameter for the GraphQL resolver is malformed. This PR brings it to parity with the Solana JSON RPC API as well as the
@solana/rpc-api
package's definition for program accounts filters.Summary of Changes
First add some test coverage to
@solana/rpc-api
for program accounts filters to ensure everything is working properly.Then, refactor the GraphQL API for the
programAccounts
query to correct the program accounts filters input. Finally, add some tests for GraphQL.Since GraphQL doesn't allow unions as input types, I had to split the two types of filters into two separate filters for the GraphQL API, then coalesce them into the same
filters
argument for the RPC.
