Redux-Form - the validation function calls an infinite loop

Question

I have a reduction form and I have a problem with the validation function. And this error occurs only on my cloud servers, on local, I have no problems with this.

Here is the check function:

function validate(values){
    const errors = {};
    let requiredFields = [
        'gender', 'first_name', 'last_name'
    ];
    requiredFields.forEach(field => {
        if (!values[field]) {
            errors[field] = 'Required';
        }
    });
    return errors;
}

And I call it that:

EditProfileForm = reduxForm({
    form: 'editProfile',
    validate
})(EditProfileForm);

And even when I run the production code in local, which now just does:

config.plugins.push(new webpack.optimize.UglifyJsPlugin({
        mangle: false
    })
)

It still works in local mode, only when the code is on the servers, I have a problem.

It sends the action: redux-form / UPDATE_SYNC_ERRORS to infinite, and I have to force Chrome to disable to stop this.
