error in selecting values from dropdown in Measurements Dashboard

[gargshruti30]

When we open Measurements Dashboard and select values from dropdowns, error is produced in web console.
@chutten Is this a bug or some JS issue?

404 means that data isn't present for the selected options. Can you be more specific about what steps you took to cause this issue?

[gargshruti30]

@chutten I selected SCALARS-PREFERENCES.PREVENT_ACCESSIBILITY and deselected 64-bit in architecture.

[chutten]

Works for me without 404s. Maybe it was an intermittent failure?

[gargshruti30]

I have tried it 2-3 times. The same error occurs.

[chutten]

Maybe try it in Firefox? Chrome sometimes has weird behaviour.

[chutten]

@gargshruti30 Any luck reproducing it in Firefox? Can you provide the exact url that is 404-ing so we can test it independently?

[gargshruti30]

@chutten I will try it in Firefox once.

[gargshruti30]

@chutten In firefox no such error is produced.

[chutten]

@gargshruti30 Can you extract the URLs that are 404-ing in Chrome? Maybe there's a clue in there.

We don't do any user-agent sniffing, so which browser you use shouldn't matter. That it does is incredibly interesting.

@chutten Now on loading the page I am getting so many 404 errors. I don't know why.

[chutten]

@gargshruti30 What are the URLs you are getting 404s for? They are truncated in the screenshot, otherwise I'd try and transcribe them out.

(the aggregates.telemetry.mozilla.org ones, to be specific)

This is the URL.
