Error: trying to merge Functional base with callThrough mock at ${path} Use overrideBy

[dewhacker]

Getting this error when attempting to mock a local module:
rewiremock('../path/to/my/module') .callThrough() .with({'./another/local/module':stub});
What is overrideBy and when should it be used?

[dewhacker]

I resolved this by using this syntax instead:
rewiremock.around( () => require('../path/to/my/module'), rewiremock('../another/local/module').with(stub) );
Not exactly sure why that worked though?

[theKashey]

overrideBy is just .by(anotherModule)
The error is about using callThrough for an module with a "non-object" export - look like it exports just a function.

PS

rewiremock.around(
 () => require('../path/to/my/module'),  
 () => rewiremock('../another/local/module').with(stub) // this should be a function call
);

// you can use .proxy to do the same
rewiremock.proxy('../path/to/my/module', {
 '../another/local/module': stub
});
