I'm getting the error "Missing visualize operator" and "Error on line 24 error near TableExpressionTerminal: ','" when editing dashboard visualization for Pantherflow query.

Issue

I created a dashboard using Pantherflow query. When trying to edit visualization settings for the dashboard, the following errors occur:

  • Missing visualize operator

  • Error on line 24 error near TableExpressionTerminal: ','

Resolution

To resolve this issue:

  1. Reformat your visualize command to use a single line instead of multiple lines

For example, change this multiline format:

| visualize line
    xcolumn=x,
    ycolumn=value,
    series=series,
    title='Example: p50 & p99 — last 7 days',
    legend=right

To this single-line format:

| visualize line xcolumn=x, ycolumn=value, series=series, title='Example: p50 & p99 — last 7 days', legend=right

Cause

This issue occurs because Panther dashboard uses a stricter parser than the regular query execution environment. While multiline visualize commands work when running queries directly, the dashboard parser does not accept this format when editing visualization settings.
