Describe the bug
hen open published app via web browser editor, I can see error 'Error executing script : 'value''

To Reproduce
Steps to reproduce the behavior:

  1. Go to web browser

  2. Add a threshold with value, which is not in your dataset
    For example:
    My table does not have 'value'
    threshold = slider("Threshold", min_val=0, max_val=100, default=50) table(df[df["value"] > threshold], title="Dynamic Data View")

  3. Check that preview is workingImage

  4. Open published app from your projects list

  5. See error 'Error executing script : 'value''
    Expected behavior
    The preview should present the same error: 'Error executing script : 'value''

  6. When I fix threshold by changing the value from table from 'value' to 'Humidity'
    threshold = slider("Threshold", min_val=0, max_val=0, default=1) table(df[df["Humidity"] > threshold], title="Dynamic Data View")

  7. The preview and published version work well

Environment:

  • OS: [e.g. iOS]
  • Browser: [e.g. chrome, safari]
  • Version: [e.g. 22]

Additional context
My hello.py with value in threshold, which raised the error

from preswald import connect, get_df, query, table, text, slider, plotly, separator, playground
import plotly.express as px

text("# Weather History Analysis App")

connect()  # Initialize connection to preswald.toml data sources
df = get_df("weatherhistory_csv")  # Load data

text("## Plot: Temperature Humidity")
fig = px.scatter(df, x="Temperature (C)", y="Humidity", labels={"x": "Temperature", "y": "Humidity"}, title="Temperatury Humidity")
plotly(fig)

separator()

df = playground(
    label="Humidity Filter", 
    query="SELECT Humidity, Summary  FROM weatherhistory_csv WHERE Humidity > 0.7"
)

separator()

sql = "SELECT * FROM weatherhistory_csv WHERE Summary = 'Partly Cloudy'"
filtered_df = query(sql, "weatherhistory_csv")

text("## Filtered Data Where Summary is 'Partly Cloudy'")
table(filtered_df, title="Filtered Data")

threshold = slider("Threshold", min_val=0, max_val=100, default=50)
table(df[df["value"] > threshold], title="Dynamic Data View")

My hello.py, which works well for preview and publish

from preswald import connect, get_df, query, table, text, slider, plotly, separator, playground
import plotly.express as px

text("# Weather History Analysis App")

connect()  # Initialize connection to preswald.toml data sources
df = get_df("weatherhistory_csv")  # Load data

text("## Plot: Temperature Humidity")
fig = px.scatter(df, x="Temperature (C)", y="Humidity", labels={"x": "Temperature", "y": "Humidity"}, title="Temperatury Humidity")
plotly(fig)

separator()

df = playground(
    label="Humidity Filter", 
    query="SELECT Humidity, Summary  FROM weatherhistory_csv WHERE Humidity > 0.7"
)

separator()

sql = "SELECT * FROM weatherhistory_csv WHERE Summary = 'Partly Cloudy'"
filtered_df = query(sql, "weatherhistory_csv")

text("## Filtered Data Where Summary is 'Partly Cloudy'")
table(filtered_df, title="Filtered Data")

threshold = slider("Threshold", min_val=0, max_val=1, default=0.5)
table(df[df["Humidity"] > threshold], title="Dynamic Data View")
