Redmine: issue custom field throws an error

Question

I've added custom field for Issue with Link type and configured URL template (as described here):

I expect that user entered value as task ID will be formatted into template, but when I try to test it this not works:

I took a look into logs, but there is not so informative record:

NoMethodError (undefined method `format_value' for #<IssueUpdateListener:0x0000000006cfbdd0> Did you mean?  format_date):

I guess, I'm working wrong with URL template or what?

Answer 1

The stacktrace indicates that the error is caused by your custom flock_notifications plugin. This plugin (or the version of the plugin you are using) might not be compatible with your version of Redmine.

You should contact the plugin author on their preferred communication channels with this report so that they might fix the plugin.
