Player Chat Message with ClickEvent.callback cause Downstream packet error

Open byquanton opened this issue 2 months ago • 6 comments

Describe the bug

If the server formats the player chat message with a click callback, geyser isn't showing the message on the client with the following error in the log. Downstream packet error! java.lang.IllegalStateException: Expected STRING but was BEGIN_OBJECT at path $.click_event.payload

To Reproduce

  1. Set up a Server that formats the Chat messages like in this Paper Guide: https://docs.papermc.io/paper/dev/component-api/signed-messages/#code
  2. Send a message from the Bedrock Client.

Expected behaviour

See the message in the client chat (without the click event functionality)

Should be resolved by https://github.com/GeyserMC/Geyser/commit/59edd3a21e37c84a3b706a52174d44525d384ea0

Tested it with 2.9.0-b966 (git-master-7375b74) and the issue is still there

Current Adventure 5 branch already has a fix: https://github.com/PaperMC/adventure/commit/1180f89a345653f6ad3a819c3ca0a7ed8e4565c9
