Intermittent issue with Yahoo datasource #60

RobWalker · 2021-07-29T05:16:28Z

When trying to update from Yahoo I get intermittent errors

The only way forward is to delete the cache.

Is it possible to treat this as a soft error for that data point and simply skip it?

This issue is fixed (very simple change) with #66 and #68 (same as #66, but with test case) - can we get one of those two merged into the main branch? @blais

It seems like at least one cause is due to an issue with mutual funds while the market is open - where there's a timestamp for the last date in the query range, but the values are all null. Example JSON response in #68

Facing the same issue/crash even with the PR #66 applied:

Woah I guess for cryptos yahoo is not that reliable: https://finance.yahoo.com/quote/DOT-USD/history?p=DOT-USD

@Nexus2k Can you reproduce the error, and post the JSON the API is returning for you when it exhibits the issue? It seems to work for me right now:

2022-02-27 price BTC-USD                      43193.234375 USD

The JSON has no null values in the prices for me, and has the "timestamp" field your error is complaining about.

Check https://finance.yahoo.com/quote/DOT-USD/history?p=DOT-USD so "USD:yahoo/DOT-USD" for some reason it has incomplete historic pricing. I've switched to coinbase for the pricing info of that now...

mbafford · 2022-03-02T13:14:34Z

@Nexus2k
Ok, your issue is actually a different issue than the one mentioned in this ticket. The API didn't return any timestamp field at all for your query. Also, your error shows you're using an older version of beanprice - the line numbers are wrong for the current code and the error you mention is solved in the latest code:

    if 'timestamp' not in result:
        raise YahooError(
            "Yahoo returned no data for ticker {} for time range {} - {}".format(
                ticker, time_begin, time_end))

Your issue was addressed in 6fe4c5e

That said, #66 and #68 (same as #66, but with test case) address the issue described in this issue - it would be nice to have them merged into the main branch.

michaelMinar · 2023-03-09T01:25:27Z

Not sure if this is related or some other issue, but I was running into this same problem of TypeError: conversion from NoneType to Decimal is not supported. I then did a pip upgrade of bean-price and tried running again, because of the fix here. I'm now getting an error with Celery and importing dbm much earlier in the process.

The caching code uses the shelve module and you didn't build dbm. Install gdbm-dev and rebuild your Python.

Thank you Blais, apologies but i'm not quite sure how to do that on macOS. Do you have a few more bread crumbs? I was just using brew to install gdbm, but brew says there is no formula for gdbm-dev. And i was also using brew to upgrade python...so I assume you just mean to do an upgrade there as well? or is rebuilding a more complicated step?

dnicolodi · 2023-03-09T18:09:38Z

Please not that Celery has nothing to do with this. There is a Cellar component in the Python module paths, but that is due to how Homebrew installs things. Your issue is due to the fact that Homebrew disabled support for dbm.gnu in Python 3.11 in favor of the dbm.ndbm backend. If you need to work with existing dbm.gnu databases, you can install the [email protected] Homebrew package.

blais · 2023-03-11T03:56:04Z

Michael: this is an issue with your setup, not a Beancount issue.
Thanks Daniele for helping out,
