What happened?

Thank you for your excellent work on this highly beneficial project! I would like to report code behavior which might possibly be improved. Thank you for your assistance with this.

Using the latest Carbon Aware SDK installed on OpenShift via Helm Cart, sometimes the query returns an error. When querying with a different location, or trying late, the problem often goes away. (All locations are valid locations reported by the locations endpoint.

Rather than displaying an error, it would be nice if the SDK took kind of action to return usable if reduced data. e.g., ignore null values, or possibly replace a null value with the average of surrounding values.

Example of error output:

$ curl -s  "http://webapi-green-software-foundation.apps.hostname.com/emissions/bylocation?location=japanwest"
{"title":"InvalidOperationException","status":400,"detail":"Cannot get the value of a token type 'Null' as a number.","errors":{},"traceId":"00-403a86f8315bc34fb13700f4dff0af2f-d7ccb83c87226e2b-01"}

Example of working query:

$ curl -s  "http://webapi-green-software-foundation.apps.hostname.com/emissions/bylocation?location=japaneast"

Possibly irrelevant, but when this error happens, the json string returned from the http call found in the log seems to always include "carbonIntensity":null. For example see the last stanza(segment?) of this json string:

@trent-s
Thanks for your report! Did you configure Electricity Maps as a data source, right?

@vaughanknight @danuw @tiwatsuka
I guess it is caused by null value in carbon intensity what Scott suggested. Carbon intensity in HistoryCarbonIntensityData is defined as following:

carbon-aware-sdk/src/CarbonAware.DataSources/CarbonAware.DataSources.ElectricityMaps/src/Model/HistoryCarbonIntensityData.cs

Lines 31 to 35 in f05dcf4

	/// <summary>
	/// Carbon Intensity value.
	/// </summary>
	[JsonPropertyName("carbonIntensity")]
	public int Value { get; init; }

What do you think?

@YaSuenag Thank you for your kind consideration. Yes I was using Electricity Maps for the data source. Thanks!

@vaughanknight @danuw @tiwatsuka
I pushed fix proposal as YaSuenag@ba68e52 . I can send PR if it looks good.

I didn't remove the data which carbonIntensity is null because EM datasource calcurates the duration from time differense between 2 elements in the array of the result. It should be kept to know valid duration.

@YaSuenag to create a PR so we can review the change and try and keep as primary focus. Thanks

[trent-s]

Thank you very much!

[YaSuenag]

@trent-s Thanks again for your report!

FYI: Carbon Aware SDK provides container image like a snapshot image. You can use it if you want to use fixed version without building. Use pre tag in GHCR: https://github.com/Green-Software-Foundation/carbon-aware-sdk/pkgs/container/carbon-aware-sdk

pre container would be built when the commit happens in dev (default) branch.

I really appreciate your excellent work and useful information!
