session.authFetch.bind(session) needed when passing as argument

[elf-pavlik]

Otherwise this.isActive() and possibly other method calls with this fail.

Many libraries accept authenticated fetch as a parameter, for example
https://github.com/rubensworks/rdf-dereference.js?tab=readme-ov-file#input-using-a-custom-fetch-function

I took a quick look at https://github.com/uvdsl/solid-rdf-store
and it looks like it gets Session and not just fetch

Can you provide more context to this issue?

You could try passing session.authFetch to any of those:

• https://github.com/rubensworks/rdf-dereference.js?tab=readme-ov-file#input-using-a-custom-fetch-function
• https://ldo.js.org/latest/guides/solid/#2-initialize-a-connected-dataset
• https://soukai.js.org/api/soukai-solid/classes/SolidEngine.html#parameters
• https://github.com/rubensworks/fetch-sparql-endpoint.js?tab=readme-ov-file#create-a-new-fetcher

All of them expect fetch function, not a Session object. If you just pass session.authFetch instead of session.authFetch.bind(session) it will fail since the function needs this.
