Response has incorrect type for parameter ErrorMessage

I get response that has incorrect TYPE of value for parameter ErrorMessage.

Free OCR API - Response states it should be TEXT, however I get COLLECTION, here sample:

{"ParsedResults":[],"OCRExitCode":6,"IsErroredOnProcessing":true,"ErrorMessage":["Timed out waiting for results"],"ProcessingTimeInMilliseconds":"7548"}

According to your docs, this rather should be:

{"ParsedResults":[],"OCRExitCode":6,"IsErroredOnProcessing":true,"ErrorMessage":"Timed out waiting for results","ProcessingTimeInMilliseconds":"7548"}

Thank you for reporting this. It this is an issue with the documentation. The OCR API returns indeed a collection for the ErrorMessage (i. e. with […]). But there is always only one string inside.
