- Line 27: Update the catch clause containing the invalid bare throw so it binds
the caught value as error and rethrows that value with throw error, preserving
the original error.

Walkthrough

resolveUserConfig now assigns docgen settings to a new object and sets its resolved root and sourcesDir. The memoized getter resets its state after an error, so a later access can retry the getter.

Possibly related PRs

• OpenZeppelin/openzeppelin-contracts#6848: Changes the same docgen configuration hook and memoized getter to address configuration mutation and getter retries.
• OpenZeppelin/openzeppelin-contracts#6841: Changes the same configuration hook and memoized getter for configuration cloning and retry after getter errors.
• OpenZeppelin/openzeppelin-contracts#6840: Changes the same memoized getter to reset its state after an exception.

Change: Bug fix

Merge Risk: High · up to 079d7

The new error handling in the memoized getter uses invalid syntax, so the docs generation task fails before it runs. This blocks documentation generation and should be fixed before merging. The fix is a one-line change: bind the error and rethrow it.

Rethrow the caught error.

throw; is invalid TypeScript syntax, so this module cannot be parsed or loaded. Bind the error with catch (error) and use throw error;.
