clicking this link I get another error as this instance is (no longer?) valid.
If I replace the instance with the one in your current account, I do indeed get this error.
Parameter values are case sensitive so you should write
(as it is the ID of the layer in the Configuration utility)
what is the time interval for which you are trying to get data? I see your requests above have dates 2015-08-26. Note Sentinel-2 mission started in the middle of 2015 and there are much less acquisitions available for that time period.
Thank you so much for the help. Now I am getting an another error like this while executing the workflow.
