Error Opening a Piston - Cannot delete in Dashboard

#1

I tried to follow this post - My piston will not load - help please

When I run either in my console (Chrome) I get the following:

ReferenceError: data is not defined
at webCoRE.min.js:897
at webCoRE.min.js:139
at m.$digest (webCoRE.min.js:150)

at l (webCoRE.min.js:106)
at webCoRE.min.js:111
at HTMLScriptElement.m (webCoRE.min.js:110) “Possibly unhandled rejection: {}”

This is the error when I try to pause it
webCoRE.min.js:127 Possibly unhandled rejection: {“data”:false,“status”:404,“config”:{“method”:“JSONP”,“transformRequest”:[null],“transformResponse”:[null],“jsonpCallbackParam”:“callback”,“url”:“https://graph.api.smartthings.com/api/token/157967e1-fc90-440e-82ba-25d7fff0b2d3/smartapps/installations/0547d58a-7938-40c5-809b-5387495cf6ba/intf/dashboard/piston/pause?id=:32540d82370226684bbd6b725389608c:&token=b908bff2-27a9-41a1-a917-94924af8de3e",“headers”:{“Accept”:"application/json, text/plain, /”}},“statusText”:“error”}

In the ST Classic app, go to Automation > your webcore instance > settings > clean up and rebuild data cache

I should have mentioned that in post 1. I did that.

I also did the console test found here (both versions)
and tried to delete in IDE found here Sorry, an error occurred while retrieving the piston data

and this - Can't Open Piston - Just Keeps Loading

Try using am incognito/private tab in your browser when logging into IDE

Of course the one thing I don’t try! Thanks @jkp. Just curious, is that due to caching?
