Get API errors now and then with no known reason

[jgoggan]

I am using your Docker for this and having it do small buys every 3 days. Sometimes, they work fine. Other times, it dies during one of the buys. I have the config set to buy $20 of BTC-USD, then $5 of ETH-USD, then $5 of DOGE-USD. I commonly get something like this in the logs:

Initiating buy of 20 USD of BTC-USD...
You bought 0.00037049 of BTC-USD
Initiating buy of 5 USD of ETH-USD...

Note that, on the Coinbase side, the ETH-USD buy actually succeeds! So, it works, but something doesn't come back properly at the client side and it dies.

I experienced the same issue and I'm about to suggest an error handling for this combined with the possibility to get notified in such a case. I just raised a pull request to introduce other alert channels - notably Pushover so that one could get active notifications right on one's phone or wrist. Waiting for response from @queball99.

Had this error yesterday and today : while the order got through yesterday it did not so today(Correction: it got through in both cases). See logs:

Yesterday:

... logs are the same.

Please note: Line numbers refer to this commit on branch support-pushover-alerts in apfelnutzer/CoinbasePro-Recurring-Buy. I got notified about the container restart at least :-).

As you can see from the logs (and the code) the error occurs when collecting the order details right upon placing a market order. Might be a timing issue. Maybe you just need to wait a little (more) for the order to be processed... I started working on this issue now.

[apfelnutzer]

The returned error code is 404 ("not found"). According to the API documentation:

If the order is canceled the response may have status code 404 if the order had no matches.

From my impression 404 seems to be sort of an intermediate state meaning the order has not been matched (yet). I added a pause of three seconds between placing the market order and getting the details to prevent the error (still testing).
