Hello , 

We have just finished the installation of Cloud Carbon Footprint using your doc "get started" but once we run the following command line : yarn start 

We get the following error :

We also tried to do another command line (in order to get some azure consumption metrics)  : yarn start-cli -i  

and we get the following error:

Hello,

Thanks for reaching out. I don't believe we've seen this issue before. I referenced the following stack overflow source:
https://stackoverflow.com/questions/69692842/error-message-error0308010cdigital-envelope-routinesunsupported
Could you please try setting this env variable from the terminal and re-running the server?: export NODE_OPTIONS=--openssl-legacy-provider

Please let me know if that helps. Otherwise, it may be a good idea to set up a time to pair together on this one and debug! If you would like to do that, could you please send over some availability you have for next week?

Thanks,

Cam

You can add the following piece of code to "node_modules/react-scripts/config/webpack.config.js"

const crypto = require("crypto");

const crypto_orig_createHash = crypto.createHash;

crypto.createHash = algorithm => crypto_orig_createHash(algorithm == "md4" ? "sha256" : algorithm);

This worked for me.
