help: bearer_invalid

What it means: The call carried no usable credential: no Authorization: Bearer header, and (for host.tool_publish and friends) no tenant_key argument either.

Likely cause: A fresh connection before signup, or a connection whose key never got attached after signup returned one.

Fix: Call signup first if you haven't; it returns a key. Then either send Authorization: Bearer <key> on the connection, or pass tenant_key as a call argument.
