@treecg/actor-init-ldes-client Error: Cannot find module '@rdfjs/data-model/lib/blank-node'

[nvdk]

I'm running into an error when trying to use the latest @treecg/actor-init-ldes-client (2.5.8):

stack trace:

ldesclient_1  | Error: Cannot find module '@rdfjs/data-model/lib/blank-node'
ldesclient_1  | Require stack:
ldesclient_1  | - /app/node_modules/rdf-ext/lib/BlankNode.js
ldesclient_1  | - /app/node_modules/rdf-ext/lib/DataFactory.js

ldesclient_1  | - /app/node_modules/@treecg/actor-init-ldes-client/index.js

This seems to be related to an indirect rdf-ext dependency https://github.com/rdf-ext/rdf-ext/issues/89 .

Edit: while writing out the steps to reproduce I think I found the culprit. We're using @rdfjs/parser-jsonld@1.2.2 to parser the output and this depends on @rdfjs/data-model@1.3.4. This seems to be incompatible with the versions used in @treecg/actor-init-ldes-client@2.5.8.

Steps to reproduce:

1. npm install @treecg/actor-init-ldes-client
2. npm install @rdfjs/parser-jsonld
3. create a index.js file similar to the one in the README
4. define start as node index.js in package.json file
5. run it npm start

In conclusion: It looks like this was caused by @rdfjs/data-model not respecting semver, the 1.3.4 releases contains breaking changes, which in turn caused the upgrade from @rdfjs/parser-jsonld@1.2.1 to @rdfjs/parser-jsonld@1.2.2 to break the app.

Pinning to "@rdfjs/parser-jsonld": "1.2.1"resolved the issue

@rdfjs/parser-jsonld is not installed when installing the ldes-client? Are you sure this dependency is still used by rdf-ext, because I don't see it in its package.json?

Any update on this?

@rdfjs/parser-jsonld is not installed when installing the ldes-client?

@rdfjs/parser-jsonld isn't, but @rdfjs/data-model is:
