Issues from gl-sdk testing on Python

[ShahanaFarooqui]

node.register is not working

Registration requires an invite code, and passing None or an empty string ("") does not work. There is currently no way to register a new node using nobody certificates.

Sample code:

from glsdk import Network, Scheduler, Signer

try:
    phrase = ("spirit couple over surprise toilet dynamic maximum attitude scrap blush outdoor science")
    signer: Signer = Signer(phrase)
    scheduler: Scheduler = Scheduler(Network.REGTEST)
    scheduler.register(signer, code="")
except Exception as e:
    print(f"\n✗ Unexpected error: {e}")

Error:

✗ Unexpected error: 'status: Internal, message: "Unable to register node: not authorized: an invite code or a partner certificate is require to register a new node (see https://bit.ly/glinvites for details", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc", "date": "Wed, 11 Feb 2026 19:30:47 GMT", "content-length": "0"} }'

---

node.recover only works with the current test mnemonic ("abandon " * 11 + "about")

Recovery fails with other seed phrases, which prevents setting up additional test nodes.

---

node.getinfo method is missing

Adding this for completeness. As discussed, the plan is to introduce a method, which would return node_info, listfunds, and listpeerchannels.

---

node.send and node.onchain_send cannot be tested

LSP setup is missing, and additional nodes cannot be registered due to the node.register issue. As a result, end-to-end send testing is currently blocked.

---

node.receive

By default, it attempts to negotiate with a missing LSP and fails as a result. Is it possible to create a standard invoice to receive payment directly from a peer?

---

node.onchain_receive

The method works, but I was unable to read the bech32 or p2tr addresses because the OnchainReceiveResponse does not expose them as public methods.

This is intended, since we either guard signups with the developer certificates we distribute on greenlight.blockstream.io, or by using one-off invite codes. The former allows us to associdate costs with a partner, that is then charged for the services they use, while the latter is a way for us to give away free nodes at hackathons and conferences.

The prod system is also probably not the place we want to encourage developers to test against, since creating a node there is very much not free, and if we cannot garbage collect them, they stick around and cause costs over time. Tests ought to be run against gl-testing (if already using pytho) or gl-testserver (otherwise, sicne the testserver is a standalone mock of Greenlight that can be tested against).

Sadly this is a wontfix as it is required for us not to fall victim to DoS attacks and resource consumption attacks.

node.recover only works with the current test mnemonic ("abandon " * 11 + "about")

Recovery fails with other seed phrases, which prevents setting up additional test nodes.

Node.recover will only work for nodes that were previously Node.registered. Since you most likely only had one invite code, you wont be able to recover the other non-registered nodes.

node.getinfo method is missing

Working on this now 👍

node.send and node.onchain_send cannot be tested

LSP setup is missing, and additional nodes cannot be registered due to the node.register issue. As a result, end-to-end send testing is currently blocked.

node.receive

By default, it attempts to negotiate with a missing LSP and fails as a result. Is it possible to create a standard invoice to receive payment directly from a peer?

Yep, I have the LSPS auto-connection that will enable the negotiation in the queue, it should be out tonight.

node.onchain_receive

The method works, but I was unable to read the bech32 or p2tr addresses because the OnchainReceiveResponse does not expose them as public methods.

Good find, I think this relates to our discussion of #[uniffi::Record] vs #[uniffi::Object]? If yes, going with uniffi::Record should address that :-)
