Error: Invalid context key

[Csstenersen]

i'm trying to send input from node-red-nordpool-api to powersaver. seem like it works fine into "Price Receiver" but fails with Error: Invalid context key in Best Save node. Please se attached json.txt with data from price receiver to best save node json.txt

what is wrong with the context?

There is obviously something wrong with the format of the data in your json file. The "start" values are numbers, but shall be strings. See Strategy input format for the correct format. Is your json output from Price Receiver? If so, please show me the data sent in to the Price Receiver.

The format was a Date.parse result after i have tried to mess around with different time formats. I hoped the node tried to make a Date object from that result.

I have now tried with date string with same result.

Yes the output is from priceReceiver.

Input now looks like this: in_to_priceReceiver.txt

Output from price receiver:from_price_receiver.txt

Maby it happens because the date string is missing the timezone offset?

[Csstenersen]

got it to work when using .toISOString() on my time format. this flow is now a success:

I'm having the same error "Invalid context key". I can't figure out what the cause is. Date is in iso format, value is a number. Attached the output of Price Receiver.

@choel83 You have a slightly different date format then what is specified. I am not 100% sure that is the reason, but it may be. See https://powersaver.no/nodes/strategy-input.html for an example of the correct format.

Thanks, missed that small difference. Changing it did the trick.
