React/redux app function not firing - react-redux

Question

Update 2:
Another update - I'm down to this one issue. The values from redux-form are being sent to the action, but even narrowed down to this:
export function signinUser(values) {
console.log('function about to run, email: ' values.get('email'));
}
I don't even see a console log entry. However, the same function with only a simple console log works:
export function signinUser() {
console.log('function about to run');
}
Update:
The only differences between the working code and non-working code is redux-form and immutablejs. I tried back-porting these to the working app and now the behaviour is the same.
I'm submitting my form and sending the redux-form values to the function, where I'm using values.get('email') and values.get('password') to pass the values to axios.
handleFormSubmit(values) {
console.log('sending to action...', values);
this.props.signinUser(values);
}
I have a login form and onSubmit I'm passing the values to a function which dispatches actions.
The code works in a repo I've forked, but I'm transferring it to my own app. The problem I'm having is that the function doesn't seem to fire, and I'm struggling to figure out where to add console.log statements.
The only console.log that fires is on line 2.
export function signinUser(values) {
console.log('function will run');
return function(dispatch) {
axios.post(TOKEN_URL, {
email: "a#a.com",
password: "a",
method: 'post',
credentials: 'include',
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json',
},
})
.then(response => {
console.log('response: ', response.data.content.token );
// If request is good...
// - Update state to indicate user is authenticated
dispatch({ type: AUTH_USER });
// decode token for info on the user
var decoded_token_data = jwt_decode(response.data.content.token);
// - Save the JWT token
localStorage.setItem('token', response.data.content.token);
console.log(localStorage.getItem('token'));
// - redirect to the appropriate route
browserHistory.push(ROOT_URL);
})
.catch(() => {
// If request is bad...
// - Show an error to the user
dispatch(authError('Bad Login Info'));
});
}
}
