Hi @steventao,

HTTP 404 does not reliably indicate a missing resource (task or attachment) but could also mask another exception (see open issue https://app.camunda.com/jira/browse/CAM-8049). Anyway, are you sure both the task id and attachment id are correct?

Edit: For example, can you fetch both task and attachment via REST API successfully?

Cheers,
Thorben
