Missing protobufjs dep?

[achou11]

installing v3.0.0-next.5 as a dependency and getting this error:

node:internal/errors:490
    ErrorCaptureStackTrace(err);
    ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'protobufjs' imported from /Users/andrewchou/GitHub/digidem/mapeo-mock-data/node_modules/@mapeo/schema/dist/proto/observation/v5.js

}

Node.js v18.16.0

Installing protobufjs in my project fixes the issue
