This is a sufficient solution for me. Note: executing the script via mongo command directly still fail on missing Buffer class.

If this is still an issue for you, would you please let us know if you've found success using the Buffer class in mongosh? Best, Edwin JIRAUSER1257066 commented on Fri, 1 Oct 2021 16:53:46 +0000: Hi moravas8051@gmail.com, Thanks for your report. MongoDB 3.6 reached end of life in April 2021 and is no longer supported, but I can provide limit guidance on this issue. The new mongo Shell (mongosh) is a fully functional JavaScript and Node.js 14.x REPL environment for interacting with MongoDB deployments and the Buffer class is also functional when using mongosh. Please let us know if you're running into any issues using the new shell. Best, Edwin
