ContentDecodingError with InstrumentsCandles

[flowtrader2016]

Hi,

I'm seeing intermittent issues with the response ContentDecodingError when using instruments.InstrumentsCandles. Appreciate any help.

Issue

Received response with content-encoding: gzip, but failed to decode it

To reproduce

event = { "ticker": "UK100_GBP", "granularity": "M15"}

granularity = event["granularity"]
ticker = event["ticker"]
  count = 500
  params = {
            "count": count,
            "granularity": granularity,
            "dailyAlignment": 0,
            "alignmentTimezone": "UTC",
        }

r = instruments.InstrumentsCandles(instrument=ticker, params=params)
oandaData = client.request(r)

stackTrace

{
  "errorMessage": "('Received response with content-encoding: gzip, but failed to decode it.', error('Error -3 while decompressing data: incorrect data check'))",
  "errorType": "ContentDecodingError",
  "requestId": "fdc8726c-bbbe-4b50-beed-e2c198a4e54f",
  "stackTrace": [

  ]
}

Look like you have an issue with the data, not with code.

I suggest you try:

• a different instrument, EUR_USD, etc.
• issue a curl call on that endpoint using the parameters you passed,

For the record: I have things running 24/5 and have no issues fetching data for multiple pairs. Just added UK100_GBP...

Conclusion: no issues

Many thanks for the response.

The error was only for the UK100_GBP with M15 data and it is intermittent (currently ok but happened yesterday and today). I also run your code 24x5 with around 20 instruments and no other issues noted. Thanks for all you do! Is there a link to buy you a coffee?

Not yet, working on it ;-)
