Cannot access file on server (HTTP 403: Forbidden)


When accessing a file using a Table Reader on the KNIME server (using a relative path), the workflow in some cases returns a HTTP 403 error (Forbidden). The Table Reader seems to be fetching the file using the REST API:

Response in workflow message overview:
Table Reader (…) - WARNING: Server returned HTTP response code: 403 for URL: http://(…):8080/knime/rest/v4/repository/(…)/filename.table:data

Since this happens in an automated workflow and in most cases accessing the file works like expected, there does not seem to be a problem with the permissions. It seems to be happening randomly but it could block the automated workflow if the file is required for processing. What could be causing this issue?

We are using the Knime Server Medium version 4.8.2 with Executor version 3.7.2



Hi @JacobW,

Welcome to our forum.

Is it possible, that the file is accessed by an other user, process or other parallel write access so that the knime server has no read access to it temporarily?

If that is not the case I will have a look at the server logs to provide you further support.
