Odd Error that hangs the UI

[yuj2i0]

Copy and paste the JSON Config below to the Editable Perspective Example

{ "version": "3.1.3", "plugin": "Datagrid", "plugin_config": { "columns": {}, "edit_mode": "EDIT", "scroll_lock": false }, "columns_config": {}, "settings": true, "theme": "Pro Light", "title": null, "group_by": [ "Country", "State", "City", "Category" ], "split_by": [], "columns": [ "Profit", "Sales" ], "filter": [ [ "Customer Name", "in", "Aaron Bergman" ], [ "Product Name", "in", [ "\"\"While you Were Out\"\" Message Book", "One Form per Page" ] ], [ "Region", "==", "East" ], [ "Category", "==", "" ] ], "sort": [], "expressions": {}, "aggregates": {} }

Choose Category as Furniture
Then backspace so it's empty, the UI hangs

Same (similar?) error when filtering on multiple values.

"filter": [
[
"Name",
"in",
"Fred"
]
]

is ok, but

"filter": [
[
"Name",
"in",
[ "Fred", "Harry" ]
]
]

causes the UI to hang with the error posted by yuj2i0.

How I found this issue was the same use as above for my own application.
This issue seems to happen in above 3.1.3 and 3.1.8 of perspective
The condition to replicate doesn’t seem to have a consistent pattern, took me a while to find an example on the editable version

Locking as the comments have devolved. We are aware there is a serialization issue with filter strings in some cases.
