syntaxError:Unexpected tokenin JSON at position 0 when viewing a customer (and only when disable "localisation/country")

I have a User Group named Operator. I noticed when I disable (uncheck) "localisation/country" under:

Code: Select all

Admin > System > Users > User Group > Operator > Edit User Group > Access Permission > localisation/country
then this error will popup:

Code: Select all

SyntaxError: Unexpected token < in JSON at position 0
OK
<!DOCTYPE html>
<html dir="Itr" lang="en">
<head>
<meta charset="UTF-8" />
<title> Permission Denied!</title>
<base href="http://food.xxxxxxxx.com/admin/" />
<meta name="viewport” content="width=device-width, initial-
If I re-enable "localisation/country", this error is gone. When I disable (uncheck) this permission again, the error re-appear. Other "localisation" permissions do not seem to be related to this error, only "localisation/country".

I need to disable "localisation/country" for my "Operator" group. I have searched for a few days but can't find a solution.

Check your error / server access logs for more information.

I have searched the forum and also Googled for days. I found many reports about "Unexpected token in JSON at position 0". Unfortunately none fit my situation. None of the cases I found is related to "localisation/country". Although I found some very closely related situation, there was no solution.

I checked the error log. Nothing useful is recorded.

Use Chrome Developer tools and check the XHR tab. See which URL is returning the error. Must be some Ajax request hitting that controller.

What oc version?
You have ocmod/vqmod extensions?

add permissions to view localisation/country or copy function localisation/country/country to controller which the user has access

and edit js function country() in admin/view/template/customer/customer_form.twig

1) This is the result under Chrome Developer Tools > XHR when accessing the error page:

Image

2) I am using OC v3.0.3.6.

3) I tried to look into error log and access log. Can't locate anything related.

4) "localisation/country" folder is originally with chmod 644. I changed to 755 and error still pops up.

Has nothing to do with file permissions.

You can see in the XHR request it's hitting the localization/country controller.

This error would also happen on the store/settings section as it expects permission to country.

What page are you getting the error on? I suspect the page needs country to work.

It might be quicker to pay a developer such as ourselves or post a job in the Commercial Support Forum.

The popup error occurs when viewing a customer profile under CUSTOMERS > CUSTOMERS > (customer name) > Edit.
And this error only occurs when Access Permission for "localisation/country" is disabled for the user.

This is my test:

1) I created a User Group called "Operator".
2) I enabled all Access Permissions and Modify Permission under User Groups > Edit. The only permission I disabled is "localisation/country".
3) Then I assigned permission "Operator" to user XXX.
4) When I logged in under XXX and go to Customers > Customers > (customer name) > Edit, the error popup when the customer profile page is loaded. If I enabled "localisation/country", the error disappeared.

I wonder if other users are facing the same thing?

Because country is needed for customer address and the AJAX request pulls that from the localisation/country controller.

Just enable access permission and disable modify permission for country.
