@tomkerkhove this has been updated to use PowerBidedicated everywhere except for ResourceType

[SurtzSean]

@tomkerkhove I'm unsure about the build failure message as I ran and tested e2e locally. Is it a problem with the pipeline, or PR?

[SurtzSean]

@tomkerkhove would you be able to take a look if you get a moment, or would there be anything more you need prior?

[tomkerkhove]

Nope, should be good - I'll take a look when I can.

[tomkerkhove]

LGTM but some comments were added - The scraper type is the main required change.

Thanks for the contribution!

[SurtzSean]

@tomkerkhove I believe I responded to all feedback

[tomkerkhove]

LGTM, sorry for the slow reviews and thanks for the contribution!
