I don't have an answer right away here but I will suggest you remove your user token and any other identifying information from there. The user token can be used to impersonate you on that app via the API if someone wanted to. Not a huge deal if this was a token create for testing on a random app with no data, but a warning just in case.
Do you have add permission in our current role on the table it is saying you do not have it on? My thought there is maybe it requires add permissions in order to merge or update things. I know it seems like a silly question as you are the admin there or at least have extra access but I am just curious.
