New query experience returns "invalid string length" for large query

In Monitor301, I executed the following query:

from(bucket: "fluxdocsd")
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r._measurement == "internal_write")

If I execute it with a 2d time range, I get an error "Invalid string length". If I shorten the time to 6h, it works. In the old data explorer, it works for both 6h and 2d. I didn't see an exception in the Javascript console.
