Player call failed

A request to a play-mode ara-player process failed: the link timed out, the player rejected the call, or a reply could not be decoded. The editor and its documents are unaffected; the world keeps its last good state.

#Common causes

• The player is busy past the request timeout (a long step or a blocking load).
• The player binary is older or newer than the host and speaks a different play protocol.
• The shared-memory or JSON-RPC link was closed mid-call.

#Fixes

• Retry the call; use ara_play with action: status to see whether the world is still alive.

• Rebuild ara-player together with the editor so both use the same protocol.

• Stop the world and start a new one from the pool.
