TypeConverting circular structure to JSON error when configuring two dataSources
Describe the bug I am configuring two dataSources - Mongo and Postgres - on my cubejs. When running any query on the Playground after configuration, the error message reads as below
TypeError: Converting circular structure to JSON
--> starting at object with constructor 'Timeout'
| property '_idlePrev' -> object with constructor 'TimersList'
--- property '_idleNext' closes the circle
at JSON.stringify (
To Reproduce Steps to reproduce the behavior:
- Edit cube.js to include two dataSources
- Open Playground.
- Select any measure and dimension and run the query. For now, I havent created any joins between Postgres tables and Mongo collections. I have defined a schema that only looks at a mongo collection.
- See error
Expected behavior
- If I remove multiple dataSources and use just 'default' - pointing to Mongo, the queries run fine.
- The error happens only when two dataSources are specified in cube.js

@smoorthyk Please use new driverFactory format that returns DriverConfig object https://cube.dev/docs/config#driver-factory
