Issue Summary

In a Confluence page, upon clicking the Total Unique issues on the two dimensional Jira Chart, we see an 'invalid filter id' error

This is reproducible on Data Center: yes

Steps to Reproduce

1. Setup Confluence(tested with 8.5.18 & 9.1.1)
2. Setup Jira(tested with 9.12.15)
3. Create an application link between Jira and Confluence
4. Create a page in Confluence
5. Insert Jira Charts macro > Select Two Dimensional
6. Enter a Jira filter > Preview > Insert
7. Publish the page
8. Click on the Total Unique issues on the right bottom corner of the Two dimensional chart.
   

Expected Results

The Total Unique issues should open in Jira

Actual Results

We see 'Invalid filter id. Filter id must be a number' error 

The link has ?filter=null instead of actual filter.

Workaround

• Clicking on 'View in Jira' link on the Two dimensional chart will open the filter in Jira
• On Confluence 8.x, Register a JIRA Two Dimensional Gadget in Confluence and use the gadget instead of the default two dimensional chart macro.
