It often happens that when I keep a dashboard.internetcomputer.org/proposal/... opened for some time while moving around other tabs in the browser, when I come back to the dashboard tab I get this error:
@ibert thanks for posting. This could have been caused by a few things; browser memory garbage collection, network issue to our IC API, or us releasing new updates to the UI/API. Is this a regular problem that you experience?
It just happened again a few minutes ago.
Same pattern: open the dashboard on Proposal 127094, move focus out of the tab (in this case, to another window on a second screen) and the error appears. The proposal tab was opened for like 1 hour before seeing the error.
