TypeError: agent.getInputProcessors is not a function error when running the Mastra Playground with the latest @mastra/core.@mastra/core: v0.20.1 (installed)mastra CLI: v0.15.1 (via npx mastra@latest dev)@mastra/core CHANGELOG (v0.14.0-alpha), I can see the processor API was reworked, and getInputProcessors() seems to have been removed. The CLI (v0.15.1) is still calling this old method.@mastra/core v0.20.x?@mastra/core to use the playground, or is there a fix coming?
