Missing NULL Handling in Time Expressions 
Tell me more
What is the issue?
The time grain expressions don't account for possible NULL values in timestamp columns, which could cause queries to fail.
Why this matters
Queries may fail when processing NULL timestamp values, affecting data analysis and visualization reliability.
Suggested change ∙ Feature Preview
Add NULL handling to the time grain expressions:
_time_grain_expressions = {
None: "{col}",
TimeGrain.SECOND: "CASE WHEN {col} IS NULL THEN NULL ELSE date_trunc('second', {col}) END",
TimeGrain.MINUTE: "CASE WHEN {col} IS NULL THEN NULL ELSE date_trunc('minute', {col}) END",
# ... Apply similar pattern to other time grains
}
