I am going to withdraw the money from my testing lightning node on mainet and I am getting this error for some reason

Yes. It has no scriptsigs. bitcoind is pretty clear here...

I'm confused: where is this transaction from, and why is this a CLN issue?

Because it is a withdrawal from core lightning? As I mention I am going to withdraw the money from my testing lightning node

[rustyrussell]

But what command made that (invalid) transaction? I would expect you to clear your node by using "withdraw all"...

I did and the transaction that created from the "withdraw" command is 020000000a2679b08b37e36d44bb49fa7c031942660803f1b8c05b80083e1b969aaaa003bc0100000000fdffffff3c0f18123a5f8d696f3f530f95d343fa8e207bd669cc655bc826c893c46198cc0000000000fdffffffc31e0ff68fec6781675db72ca0d378d02db56456030becf25dbe0ac3cd20b7aa0100000000fdffffffed7f81bf64307f6cd25cef7278ffc732264233968368fc3917793fed2d77bdf50000000000fdffffffce3427d3fe46a8f146fd824617e499c8564d7f974e2d64cd47c8d5d0751a27180200000000010000007421b348c27c482b3da1abbf469a6589558150f9bafc2fa230c03cc53751688c0000000000fdffffff939b7b69713e8ed97d4a75d863ce47128d26a60bb9e67438b20bf6f9f2845f560000000000fdffffff3807358665857e2d4724d4aa1f0afc63356136da42b0c5f2bc8caf662ed311bf0000000000fdffffff805a1073d4285d890f48d06970c8d31f8b45fab358b567d8336cc83de649f35e0000000000fdffffffe66d972bf95478ff766af46e0878dfcc0c1392b9b2d73aef9a9a33dd561bb6de0100000000fdffffff0206e5940000000000220020e15b3cbf348699e937d60e319fbe7849af5e061d2b498a8d49b4612b4c9f4014a861000000000000225120bfd5121ff10f4e62aaadd1630a1404666b2bf8c9b79db0d35b245f6daaad815a521a0e00

I had to use sendrawtransaction because I lost the withdraw result, and I am waiting for the inputs to be unreserved again. The error with "withdraw" will be the same due sendrawtransaction under the hood anyway!

[rustyrussell]

Did you get that transaction from the logs, or the return from the withdraw command? Because it's clearly unfinished... 🤔

[vincenzopalazzo]

No Rusty, this is the result that I get from the "withdraw" as specified inside the previous message!

[rustyrussell]

Right, so the bug is withdraw returning an unsigned tx. You should, meanwhile, be able to sendpsbt the psbt it returned...

Not sure because I lost the output of withdraw but If helps I should be able to try again to help in fixing this issue
