-------------------------------------
Hi [~shahrs87] and [~vinayrpet],
Thanks for your earlier work on this.
I saw that the latest patch does handle ErrorReportAction the same way but
there was a comment below:

Yes. Rushabh S Shah is right. I had already checked about this.
ErrorReportAction doesn't need to be handled.

This is related to [~hitliuyi]'s comment (thanks Yi). It seems reasonable to
handle both, but because of the above comment, I have a question, did we
discover something new such that we made the the change in ErrorReportAction?
At least this seems to be a discrepancy between the comments and the patch.
Thanks.
