Hello everyone, I am using addAllTablesUsedInQuery function to create a catalog. However, if there is a JSON type column in the table, I am getting null pointer exception.

You can see the exception in the screenshot below:

Thank you for reporting this!

I found the cause of this bug. I'll address it and release a new version of the toolkit in the next couple of days.

Hello @ppaglilla,

Same issue persists with the function addAllFunctionsUsedInQuery when a BigQuery function holds a return type of JSON type. Since you plan to patch a similar bug, I want to contribute by revealing another unexpected behavior.

Thank you for your support 🙏

Thanks for bringing the functions case up as well!

It is caused by the same problem as the tables one, so they'll be resolved together.

Fixed in release 0.4.1. Thank you for reporting and apologies for the delayed release!
