how can I completely disable the cache

Hello, how can I completely disable the cache?

I modified cache.xml, refreshed the cache settings, and restarted the service, but Helical still reports cache-related errors.Processing: EfwServiceException.txt… ERROR ServiceUtils:112 - An exception has taken place. The stackTrace is com.helicalinsight.efw.exceptions.EfwServiceException: Could not obtain cache.

I want to disable the cache because I keep getting errors when saving the metadata of an API data source. My original API data source was able to create and save metadata successfully. However, after I modified queryParams, I created a new data source and tried to save it, but it failed with an EfwServiceException.

Even if I change queryParams back to the original settings, the same error still occurs. I also cleared the cache, but the error remains.
