Event store projections failing on a regular basis

EventStoreDB

Apologies, I meant to say “good state” instead of “good place”.

After checking the administrative events, I saw multiple errors :

  • Application Error
  • .Net Runtime

I am joining some of those errors below

Hello Pieter

What would you suggest I do ?

Resubmit all of the data again ? Delete projections, then recompute them ?

How could I avoid this in the future ? Avoid projections ?

Best regards
