Bitcoin Core Wallet with Sparrow Wallet as coordinator sighash issue

[Julian7586]

Hello, I'm hoping someone can help me with an issue I'm having with my bitcoin core wallet. I have an offline laptop running ubuntu with core 29.4 installed as the signing device. I also have another computer online running core and sparrow wallet 2.5.3 as a coordinator. I copied an Xpub from the offline machine into sparrow and everything looks good. When I create a transaction in sparrow and try to sign it on the offline machine I get an error message. "failed to sign. Specified sighash value does not match value stored in psbt". The Xpub I copied was the m/84 and sighash on sparrow is default "recommended" setting.

The details in Sparrow side is vague.
Try to compare the displayed descriptor in your Sparrow wallet's settings, Descriptor->Show... button
And Bitcoin Core's listdescriptors command.

Or post the snipped versions in your reply,
For your privacy, snip the extended public key (xpub) to just show the derivation paths and script types of each descriptors.
