timestamp of 1900 is older than 100 years,
so yahoo responds with error:
GDEVW: 1d data not available for startTime=-2208994789 and
endTime=1687780922. Only 100 years worth of day granularity data are
allowed to be fetched per request.
this should fix it,
something similar was proposed here:

Improve split-repair of multi-day intervals. Because split error can occur within a multi-day interval, e.g. mid-way through week, need to repair each OHLC column separately
Increase robustness of repair 'Adj Close'
Limit price-repair recursion depth to 2
Various important changes to yfinance logging:
Remove handler from YF logger as breaks standard logging practice.
Improve 'download' log message grouping
Move custom DEBUG log formatting into 'yf.enable_debug_mode()', which if called adds the handler. The custom DEBUG log formatting is:
- 'MultiLineFormatter' improves appearance of multi-line messages in any logging mode. Adds leading indent to all lines below first, to align with the first line which is indented by %levelname%.
- Whitespace padding is added to end of %levelname% string up to 8 characters. This resolves different level strings e.g. INFO & DEBUG creating different indents. But this only automatically applies to first line of message - for multi-line messages, 'MultiLineFormatter' extracts amount of padding and applies to all other lines.
- Add leading indent proportional to function depth, because DEBUG generates a lot of messages particularly when repairing price data - same function can be called recursively. Implemented in 'IndentLoggerAdapter', a simple wrapper around the logger object.
- 'log_indent_decorator' inserts 'Entering/Exiting %function%' debug messages, helps organise.
Main change is fixing price-repair of 1d 'Adj Close'. 1d repair uses 1h data, but 1h is never div-adjusted. For correct 1d 'Adj Close', extract div-adjustment from the good 1d data, and calculate it for any bad 1d data. A new unit test ensures correctness.
Other changes:
- bug fix in split-repair logic to handle price=0
- improve unit test coverage on price dividend
- add 1wk interval to split-repair unit test
Stumbled upon another type of 100x price error - Yahoo may switch a symbol from e.g. cents -> $ on some recent date, so recent prices are 100x different. The new split-repair is perfect for this - set change to 100 and ignore 'Volume'.
An out-of-range dividend was breaking merge with 1mo-prices, so fixed that. Also replaced the mega-loop with Numpy, much clearer now. Improved its tests.
Recent release action generated deprecated error: "Node.js 12 actions are deprecated. Please update the following actions to use Node.js 16: actions/checkout@v2, actions/setup-python@v2."
So simply increasing versions to match latest GitHub usage docs, hopefully works.
