Uncaught TypeError: e.data.search is not a function - Smashing/smashing GitHub Wiki
From smashing issue #68
Browser extensions (e.g. Angular Augury) may call postMessage, which is used by the dashboards. Resulting in an exception as follows:
Uncaught TypeError: e.data.search is not a function
at handler (application.js:1325)
handler @ application.js:1325
application.js:1325 Uncaught TypeError: e.data.search is not a function
at handler (application.js:1325)
handler @ application.js:1325
In this case you can either disable the extension, or ignore the errors in the browser JavaScript console.
