Could not find the project with the ID ${projectId}.

Error message

Could not find the project with the ID ${projectId}.

What it means

Thrown inside `Reset.getProject()` when `--projectId` is supplied but no project row matches that ID in the project table (`ProjectRepository.findOneBy({ id: projectId })` returns null). This is a guard before `OwnershipTransferService.transferAllResources` is called with a non-existent destination.

Solutions

Verify the project ID exists with `n8n list:project` or by querying the `project` table directly.
Re-copy the ID from the n8n UI project settings and rerun.
If the project was deleted, choose a different target or create a new one.

Example fix

// before
n8n ldap:reset --projectId=Ox8O54VQrmBrb4q
// after  (after confirming correct ID)
n8n ldap:reset --projectId=Ox8O54VQrmBrb4qL

Defensive patterns

Strategy: validation

Validate before calling

const project = await projectRepo.findOneBy({ id: projectId });
if (!project) throw new Error(`Project ${projectId} does not exist; verify the ID.`);

Prevention

Look up project IDs via the UI or `project` table immediately before running the command.
Avoid copy-typing IDs across environments.

When it happens

Trigger: Passing a typo'd or stale project ID; referencing a project from a different n8n instance; passing an ID with extra whitespace or wrong casing.

Common situations: Copy-paste errors; cross-environment ID confusion (dev vs prod); the project was deleted between the time the operator looked it up and ran the command.
