i had the same problem. Like the above mentioned question.

i try your answer . But no change is happend. The same errors will be shown .

Thanks for your answers Arif, It shows same error.

In this access control record, try without specifying 'Group', keep this field empty so that it will give read permission globally.

This error normally show when any of the user group belongs for user does have the permission to read that model.

I checked at my end, here it works. Please check is there any 'Record Rules' for model object. If so remove / add proper group it and try.

Same error throwing. I am stuck with this error in last two days.

Can you help me from the starting?

Still showing the error,Arif. Dont know to fix it.
