avoid npe when the extracting signature from a bip322 psbt
What changed, and why it matters
This commit fixes a null pointer exception (a common software crash) that could occur when Sparrow Wallet tried to extract a signature from a special type of Bitcoin proof-of-ownership transaction (BIP322 PSBT). Without seeing the actual code change, we can only say it appears to be a defensive bug fix that prevents a crash during signature handling. There is no evidence in the commit message that this was disclosed or treated as a security vulnerability by the project.
Obtain and review the actual diff for this commit to determine whether the NPE could be triggered by malformed PSBT input and whether the fix fully addresses the root cause. Consider whether additional input validation or fuzz testing of BIP322 PSBT parsing is warranted.

Evidence from the diff
The commit title indicates a fix for a NullPointerException (NPE) during signature extraction from a BIP322 PSBT (Partially Signed Bitcoin Transaction). BIP322 signatures are used for address/message ownership proofs. The fix is a one-line change in the ‘drongo’ module. NPEs in signature extraction paths can sometimes mask deeper issues, but the supplied materials do not include the diff, so the exact variable, trigger condition, and security implications cannot be determined.
