onCustomSignParam.getHeader result is not an object

Error message

onCustomSignParam.getHeader result is not an object

What it means

Thrown during avatar sign-in when the app-provided onCustomSignParam.getHeader callback returns something that is not a plain object (checked via Object.prototype.toString !== '[object Object]'). The SDK merges these headers into the sign request; a function, null, or class instance triggers this.

Solutions

1. Make getHeader return a plain object of string key/values
2. Fix consumers whose getHeader returns Headers/functions/undefined
3. Validate the callback's return before passing it into SDK config

When it happens

Trigger: Thrown at console/frontend/src/utils/avatar-sdk-web_3.1.2.1002/xrtc-player-BJTnVhG9.js:12870 when the library encounters an invalid state.

Common situations: See trigger scenarios.
