Embedded Liveboard Filter 404 error

Hi TS Team, I hope you're doing well! We have a Liveboard embedded in our customer portal with row-level security enabled. While users are able to access and view the Liveboard without issues, they encounter a 404 error ("Not Found - The page you requested could not be found") when they try to click on the date filter. I’ve already reviewed their group privileges but didn’t notice anything that might restrict them from using filters. Is there something specific I should be checking or adjusting to resolve this? Thanks in advance for your guidance!
