Error message

DATA_NOT_EXIST

What it means

DataPermissionCheckTool.checkRepoBelong throws BusinessException(ResponseEnum.DATA_NOT_EXIST) when the Repo argument is null. The method is a permission gate: after the null check it compares the repo's spaceId/userId against the current request's space/uid and also throws DATA_NOT_EXIST (or denies) when ownership does not match. The intent is to make a non-existent record and a record the caller may not see indistinguishable.

Solutions

Verify the repo id exists with repoMapper.selectById(id) before calling checkRepoBelong, and return a 404 to the client if null
Check the request payload/path variable — a missing or malformed repoId resolves to no row
Confirm the row is not soft-deleted and belongs to the environment/space you are querying against
Catch BusinessException with code DATA_NOT_EXIST at the controller layer and map it to HTTP 404

Example fix

// before
Repo repo = repoMapper.selectById(id);
dataPermissionCheckTool.checkRepoBelong(repo);

// after
Repo repo = repoMapper.selectById(id);
if (repo == null) {
    throw new BusinessException(ResponseEnum.DATA_NOT_EXIST); // or return 404
}
dataPermissionCheckTool.checkRepoBelong(repo);

Defensive patterns

Strategy: try-catch

Validate before calling

Repo repo = repoMapper.selectById(repoId);
if (repo == null) { throw new BusinessException(ResponseEnum.DATA_NOT_EXIST); }

Type guard

if (repo != null) { dataPermissionCheckTool.checkRepoBelong(repo); }

Try / catch

try {
    dataPermissionCheckTool.checkRepoBelong(repo);
} catch (BusinessException e) {
    if (ResponseEnum.DATA_NOT_EXIST.getCode().equals(e.getCode())) {
        return ResponseEntity.notFound().build();
    }
    throw e;
}

Prevention

Always null-check mapper lookup results before calling permission tools
Return 404 (not 500) when the entity is absent
Clean up dependent records when deleting repos to avoid stale references
Log the failing entity id to speed up triage

When it happens

Trigger: Calling checkRepoBelong(repo) with a repo loaded by repoMapper.selectById(id) that returned null — i.e. an id that does not exist in the repo table, a soft-deleted repo, a wrong-tenant/space id, or an id from a stale client reference.

Common situations: Client passes a deleted or mistyped repository id; DB row was removed between listing and access; caller forgot a null check after selectById before invoking the permission tool; cross-space reference leaks an id the user never owned.

Understand the failure class

Background: "Not found" and "does not exist" errors: why "Task not found", "No such folder", and "Can't find" fire when a lookup comes back empty — this error's family across 14 libraries.
