Obsidian Page Parameter Filter Block Attribute Error

[matthewmeekins]

Description

When trying to use the page parameter block to filter on Group Attributes I get an uncaught error of "Unexpected end of JSON input". This happens when adding a filter with Field Type "Attribute" and then choosing an Entity Type. It seems to not matter which Entity Type you choose. I'm including a short video because I've never seen something break like this in Rock.

Actual Behavior

Adding a filter type of Attribute gives an error.

It's expected that the attribute filter should be added to the block without an exception.

Steps to Reproduce

• Open Block Settings
• Click the plus button under Filter Type
• Choose a Field Type of Attribute
• Select any Entity Type
• See error

We're also seeing this same error with Service Jobs that have attribute field types:

Before removing the attributes from the job and re-adding them during testing locally, we would receive this error when trying to click 'Save':
