Summary:
This diff exports the last 30 mins of logs. I noticed that the export can become massive, if Flipper is running for a long time and if all the logs are exported. Due to this I have noticed that the byte size of the exports has been huge and most probably causing out of emory exception in our end point to upload the trace.
Just exporting Logs plugin, size of Flipper trace is 1.8MB, mind that my Flipper was just open for few mins.
