Thanks for reporting. The _display_ of this warning starts with my 14878f3f9 (ob-core: Display warning on failure to read results, 2020-05-21). Here's the associated thread on the mailing list: <https://orgmode.org/list/2449663.1588516...@apollo2.minshall.org>. On that commit's parent (eecee2266), the error is triggered and caught in the same way, but "Error reading results: (beginning-of-buffer)" is buried in the messages buffer rather than being displayed as a warning. I'll need to take a closer look at what's going on, though I wouldn't be surprised if it's been around for a long time.
