Loading https://...?_host__Info=... disturbs future loading of other pages

[SoftTimur]

Hello,

I just discovered OfficeJSHelpers. I added console.log("OfficeHelpers.Utilities.host: " + OfficeHelpers.Utilities.host) and console.log("OfficeHelpers.Utilities.platform: " + OfficeHelpers.Utilities.platform) to my website. It works fine, but when I load in a browser https://localhost:3000/try?_host_Info=excel|web|16.00|en-us|7fe9b4e9-d51e-bea5-d194-c817bc5ed4bc|isDialog#%2Ftry%3F_host_Info=excel%7Cweb%7C16.00%7Cen-us%7C7fe9b4e9-d51e-bea5-d194-c817bc5ed4bc%7CisDialog (see why I have this url here), it considers EXCEL as host and OFFICE_ONLINE as platform, and raised an error Uncaught TypeError: Cannot read property '_appName' of null in excel-web-16.00.js.

What is worse is that, it disturbs the loading of other pages. Now, all the pages like https://localhost:3000/home or https://localhost:3000/try in a browser returns EXCEL as host and OFFICE_ONLINE as platform, and raised an error Uncaught Error: Sys.ArgumentNullException: Value cannot be null. Parameter name: conversationId in excel-web-16.00.js. The only solution is to clearing browser history data.

I think it is a bug...

Thank you

@Zlatkovsky something that you'd want to take a look at.. Are we caching the value of host & platform? Also why are url parameters even a source for determining paths? I assumed that sessionStorage would provide that information when loading in Office.js
