202 error from Computer Vision

Jon Behr 6

Hi,

I'm getting a 202 when I POST: https://{endpoint}/vision/v3.2/read/analyze

(I've used my endpoint from my account for this project).

Content-Type: application/json

Ocp-Apim-Subscription-Key: [my subscription key]

{"url":"@imageurl"}

where my @imageURL = [https://storage.googleapis.com/media.landbot.io/251624/customers/144015905/MOPRQJ5LTDE40PM5M6710T5FIOVCMJ4V.png

The response body is as follows:

"No JSON response\n"

Whereas I was expecting a response header field called Operation-Location. The Operation-Location value is a URL that contains the Operation ID to be used in the next step.

Why might this be? Thanks.

I've tried this version of the POST:

https://uksouth.api.cognitive.microsoft.com/vision/v3.2/read/analyze

and it works in the API playground but NOT from my cURL environment.

Ok, got it - your documentation is wrong - the endpoint isn't needed - it should be host name - e.g. UKSouth for me.

Actually - see below comment - it is STILL not working for me with this - it works in the API console but not from my own cURL. So frustrating!!

Here's my layout:

and this is what returns:

And here it is working on your console with all the same info:

Jon Behr Should also work with curl unless the headers are stripped or the image URL is not passed correctly. This worked for me as seen in the screen shot.

curl -v -X POST "https://eastus.api.cognitive.microsoft.com/vision/v3.2/read/analyze" -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: <your_key>" --data-ascii "{\"url\":\"https://storage.googleapis.com/media.landbot.io/251624/customers/144015905/MOPRQJ5LTDE40PM5M6710T5FIOVCMJ4V.png\"}"

Subsequent GET of the operation location also worked to get the results.

curl -v -X GET https://eastus.api.cognitive.microsoft.com/vision/v3.2/read/analyzeResults/<operation_location> -H "Content-Type: application/json" -H "Ocp-Apim-Subscription-Key: <your_key>"
