feat(auth): Update ActionCodeSettings to support LinkDomain and deprecate DynamicLinkDomain

[graeme-verticalscope]

Discussion

Add the LinkDomain field to the ActionCodeSettings struct, this new field enables migrating off of firebase dynamic links, which is deprecated and will be unsupported soon.

See #681, I was asked to create a second PR targeting master branch. Original PR is #682

Thanks for putting this together!

Thanks for the contribution! The base branch for PRs should be pointed to dev (I just changed it here), please update the feature branch and let me know if you run into any issues.

I guess you'll want to close either this PR or #682. I had originally created a PR targeting dev, but was recently asked to make one targeting master

Approved #682 too.

Hi @graeme-verticalscope, thanks for getting started on this.

Can you add some error logic similar for what we have for dynamicLinkDomain:

firebase-admin-go/auth/user_mgt.go

Line 524 in d515faf

invalidDynamicLinkDomain = "INVALID_DYNAMIC_LINK_DOMAIN"

For invalidHostingLinkDomain the backend error should be "INVALID_HOSTING_LINK_DOMAIN"

firebase-admin-go/auth/user_mgt.go

Lines 554 to 557 in d515faf

	// IsInvalidDynamicLinkDomain checks if the given error was due to an invalid dynamic link domain.
	func IsInvalidDynamicLinkDomain(err error) bool {
	return hasAuthErrorCode(err, invalidDynamicLinkDomain)
	}

firebase-admin-go/auth/user_mgt.go

Lines 1445 to 1449 in d515faf

	"INVALID_DYNAMIC_LINK_DOMAIN": {
	code: internal.InvalidArgument,
	message: "the provided dynamic link domain is not configured or authorized for the current project",
	authCode: invalidDynamicLinkDomain,
	},

Also ensure these are included in our tests:

firebase-admin-go/auth/user_mgt_test.go

Lines 2149 to 2153 in d515faf

	"INVALID_DYNAMIC_LINK_DOMAIN": {
	IsInvalidDynamicLinkDomain,
	errorutils.IsInvalidArgument,
	"the provided dynamic link domain is not configured or authorized for the current project",
	},

firebase-admin-go/auth/email_action_links_test.go

Lines 293 to 296 in d515faf

	cases := map[string]func(error) bool{
	"UNAUTHORIZED_DOMAIN": IsUnauthorizedContinueURI,
	"INVALID_DYNAMIC_LINK_DOMAIN": IsInvalidDynamicLinkDomain,
	}

Thanks!

@jonathanedey, thanks I added the error code you mentioned!

You may want to check that the code and message are correct here:

"INVALID_HOSTING_LINK_DOMAIN": {	code: internal.InvalidArgument,	message: "the provided hosting link domain is not configured or authorized for the current project",	authCode: invalidHostingLinkDomain,	}, 

I used the same code and a similar message to the existing dynamic link error mapping.

[jonathanedey]

LGTM with one change, thanks!

[jonathanedey]

Good call out, lets go with the following to match the node sdk:

the provided hosting link domain is not configured in Firebase Hosting or is not owned by the current project

[graeme-verticalscope]

Great! I updated the error message.

[egilmorez]

LG with possible nit, thanks!

[graeme-verticalscope]

Let me know if there's anything else I need to do, otherwise I'm assuming this can be approved and merged by a repository maintainer :)

[jonathanedey]

That's everything, thanks again @graeme-verticalscope for putting this together!
