Code example in 02 Managing Data errors

[MinmoTech]

When running the code in https://github.com/orbitdb/field-manual/tree/main/code_examples/01_Tutorial/02_Managing_Data I get the following error:

index.min.js:2 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')

I simply downloaded the files and started a webserver with python -m http.server 8000
