@Sainath N @Maik Skoddow here is the role that admin and i am using this . i have been using it everyday and yesterday was working and yesterday i do not change any permission. not sure why today it is broken

@chercm : I tried directly from the browser and gave admin credentials of my PDI, and below is the result. I suspect there is some issue or any insufficient roles in your user profile that's blocking the result.

@chercm : This clearly states that the user you are trying with has some external role, which is blocking the content. As you mentioned that it used to work earlier, check if there are recent changes to the user profile or the roles assigned to the user. Could you make sure that you removed the "snc_external" role from the profile?
