Unable to send event to backend: rapid_response

While debugging the issue it turns out that we already have fixed it in an earlier version of Rapid Response xBlock some time ago.

The line of code that this error refers to has been fixed in an earlier PR https://github.com/mitodl/rapid-response-xblock/pull/93 to only send our events in case there is absolutely one submission and the fix was released in Rapid Response xBlock - 0.1.0.

Looking at the sentry log I see we are still using version 0.0.9 and installing Rapid Response version 0.1.0 or above should fix this error.

I opened an issue in salt-ops. I'm not sure exactly how we specify the updated version though.

Unless we hear this is urgent from the residential MITx team, we'll wait to pick up this fix with the maple release.

This was fixed for maple in https://github.com/mitodl/ol-infrastructure/commit/a33dff0c39985249205d861c4028792b405f3ff7
