Accumulator Stages with $project "-Infinity" returned by db

Hi everyone,

I’m trying to follow lecture 2 in chapter 3 and am getting different result after typing in exactly the same command as shown on the video. I should be getting:

{ “max_high” : 07 }

but instead getting:

{ “max_high” : -Infinity }

my query below:

Thank you in advance!

Just a small typo @krasy8. It should be avg_high_tmp and not avg_high_temp

You are honestly a proper “fixer”, Mr Bond!

I have no words, but thank you kindly!

Problem solved!
