Can Jira Sprint Burndown track hours as estimation points instead of story points?

[Martin Blomgren-Sköld]

In a project of mine we use hours as "story points". With these settings, my sprint burndown will not show our progress. Is there a way to make the sprint burndown work or do I need to switch to story points?

This looks like an error based on a custom workflow. Please contact your JIRA administrator to have this resolved. 

Based on what is shown - there is some code which is running where a 'replace' function is trying to be executed. 

If you are running the method as part of the ScriptRunner plugin - you need to fix your code: 

yourString.replace("old", "new")
