com.dokar.quickjs.QuickJsException: TypeError: not a function

[TelephoneTan]

can't know what is not a function, how can I fix it if I don't know the variable or the function name?

[dokar3]

I'm not sure if this is possible to fix since 'TypeError: not a function' comes from the engine.

I searched the code, it seems that this error message comes from this library, there are some string literals look exactly the same as this error message in the code.

The location? I don't really have an impression of this.
