Inquiry about Handling FAILED Responses in Batch Statistical API

[Sagri]

Dear Sentinel-Hub Support Team,

I am experiencing an issue similar to the one described in the following URL:

Batch Statistics API sending failed responses

Is there an issue with the Batch Statistical API? I have been trying to extract stats but I get failed outputs. The dashboard shows all steps and also my PUs are being consumed but the json responses show status FAILED. The same script was extracting data previously for different set of dates.

Given that this issue may occur, I need to verify all the JSON files downloaded to a specified S3 bucket by the Batch Statistical API to check for any responses marked as FAILED. If any are found, I would need to create a new request for those specific responses. This process is time-consuming due to the need to read files from S3, so I would like to avoid it if possible. Is there any way to know in advance if a response has FAILED?

Additionally, if a significant number of polygons have FAILED, it could result in a substantial consumption of Processing Units (PU). In such cases, is it possible to get a refund for the consumed PU?

Thank you for your assistance.

Best regards,

Sagri
