Error on any js api command execution

[Tolsi]

After every command in javascript console, I see an error on the right text area:

21:22:59.800784 TypeError: Cannot read property 'apply' of undefined at Object.api (src/index.ts:81:33) at handleRpcMessage (frida/runtime/message-dispatcher.js:49:1) at handleMessage (frida/runtime/message-dispatcher.js:29:1)

or

21:33:39.321790 TypeError: Cannot read property 'then' of null at handleRpcMessage (frida/runtime/message-dispatcher.js:50:1) at handleMessage (frida/runtime/message-dispatcher.js:29:1)
