In the function extractParams at https://github.com/episerver/content-graph-js-sdk/blob/main/samples/musicfestival-frontend-react/src/helpers/urlHelper.ts#L20, contentId and workId is read from the payload of of the previewToken :
const contentId = payload.c_id && parseInt(payload.c_id!.toString());
But the documentation at https://docs.developers.optimizely.com/platform-optimizely/v1.4.0-optimizely-graph/docs/on-page-editing-using-content-graph#setup-decoupled-site states that we should not depend on the content of the token :
"Note
The preview token is only meant to be used to query data from Optimizely Graph. Do not depend on the contents of the token itself as they are subject to change in the future.
