Hi,
thanks for the report!
This indeed works for me, is there anything I might be missing?

Comment 2

[Julien Wajsberg [:julienw]]

Ah sorry, I just understood this is about the _export_. Let me look.

Comment 3

[Julien Wajsberg [:julienw]]

I don't see the problem myself either. The export looks good.
Can you share your export in the bug?

Remember JSON files need to be read in UTF-8.

import this file and switch to it

[Julien Wajsberg [:julienw]]

The JSON itself looks right, but I see that the import seems to be wrong indeed. So I reproduce with this STR, thanks!

The error is likely lying somewhere around https://searchfox.org/mozilla-central/rev/007b66c1f5f7a1b9a900a2038652a16a020f010c/devtools/client/performance/modules/io.js#69.

I believe that this report is related to the old DevTools Profiler.
The Performance panel in DevTools now points to the new Firefox profiler available at profiler.firefox.com
Closing as Invalid bug
