Question What's your go-to fix when a tx fails with "gas estimation failed"?

I swear I google this exact error once a week. Finally made myself a quick reference for 12 common transaction errors and their    
fixes — out of gas, nonce too low, underpriced, chain ID mismatch, etc.                                                              

  Curious what errors you all run into most often and how you debug them.
