1. You get a success because even if we can't unlock the LCP license properly, you should still be able to read the publication metadata which are not encrypted. For example, to import the publication in a bookshelf.

2. This error happens when you are trying to open a license with a profile that is not compatible with your R2LCPClient.framework. Some frameworks are generated for testing only and can't open production licenses.

You can see the list of known profiles here: https://readium.org/lcp-specs/registries/profiles

Identifier	Description	Reference
http://readium.org/lcp/basic-profile	Basic Encryption Profile 1.0, used for testing purpose only	Readium LCP specification
http://readium.org/lcp/profile-1.0	Production Encryption Profile 1.0, defined by EDRLab	EDRLab website

The profile used by the LCPL file is listed under the JSON key encryption/profile, for example:

{
	"provider": "https://www.edrlab.org",
	"id": "69f0547a-edef-4a99-8212-7512745268b1",
	"issued": "2021-11-08T11:00:28Z",
	"encryption": {
		"profile": "http://readium.org/lcp/basic-profile",
        ...

If you have any issue making your R2LCPClient.framework work with specific license profiles, please contact EDRLab for additional support.

To add to this discussion: the LCP module exists in two variants: Test and Production.
The Test variant can open Test LCP licenses only. Test LCP licenses are generated by an LCP Server in Test Mode, e.g. the codebase directly downloaded and compiled from Github (https://github.com/readium/readium-lcp-server).
The Production variant can open Test and Production LCP licenses. Production LCP licenses are generated by an LCP Server in Production Mode, e.g. the codebase downloaded from Github, modified to handle the Production Encryption Profile 1.0 defined by EDRLab and compiled.

Developers willing to try an LCP development start with the Test LCP module, using instructions given by EDRLab (contact (at) edrlab.org). And they test their development with Test licenses. If they try to open a Production license, they will get the error above.
After successful testing, signature of LCP Terms of Use and payment of a fee, they get access to the Production LCP module (via EDRLab again). And then they can test their dev with Production licenses, obtained from any Production LCP server on the market.
