Error while trying to import an custom vision project

TolgaE 1

Hi,

I have been using this documentation: https://learn.microsoft.com/nl-nl/azure/cognitive-services/custom-vision-service/copy-move-projects to move my project from one Azure Account to another.

After succesfully retrieving the information needed to import the project I get the following error:

{
"code": "BadRequestInvalidImportToken",
"message": "Import token was not valid."
}

I have tried to import the project via Postman, cURL and via the microsoft site itself.

I am pretty certain the token is valid and have no idea why the import does not work. It also does not work when I enter the subscription key and endpoint of the source account. I still get the same error.

the POST (edited for sensitive information) I try to do is:

https://xxxxxxx.cognitiveservices.azure.com/customvision/v3.3/Training/projects/import?token=https://irisprodwetraining.blob.core.windows.net/prjexp-xxxxxxxxx/project-export-info?sv=2019-12-12&se=2021-03-10T11%3A53%3A16Z&sr=b&sp=r&sig=%xxxxxxxxxxxx%3D

Below TIP is from this resource: https://learn.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/copy-move-projects#export-the-project

If you get an "Invalid Token" error when you import your project, it could be that the token URL string isn't web encoded. You can encode the token using a URL Encoder here: https://meyerweb.com/eric/tools/dencoder/

@TolgaE I have tried to import a project using the steps from the document with curl and it seems to work as expected.

I think the reason for your error could be the SAS token might be expired. If you could copy your token and paste it in a browser window it should download a project info file, if it fails though a new token might be required.

Hi. Thanks for your answer.

When putting the url of the token it downloads a project info file which is valid and contains information about the project, but still getting the 'import token was not valid' error even with curl.

@TolgaE Thanks for checking. If the file is being downloaded then I think the token is valid and the issue might be with the request that might be getting corrupted. Do you mind pasting the command without your token and keys so I can review if there is any issue?

Hi. I've got it working. I changed the endpoint from my own specific endpoint to https://westeurope.api.cognitive.microsoft.com/customvision/v3.3/Training/projects/import and now it works!

hi all, I get the same error. I tried the other solutions but not come far. If I change to https://westeurope.api.cognitive.microsoft.com/customvision/v3.3/Training/projects/import or try to do it with another model it gives the same error. the file is being downloaded if i call the token in a browser. ![88419-untitled.png][1] [1]: /api/attachments/88419-untitled.png?platform=QnA

anonymous user-8611 Is the training key valid for your project where you would like to import? You can get the key directly from custom vision portal if required.
If this is valid and you are still receiving an error then I would request to raise a support case to check the failed request id. The support team would be able to advise if there is any issue with the token generated with the export request.

@romungi-MSFT maybe it's better to explain my steps step for step (many many thanks in advance): Step 1: Extract the project-id and training key from the source model: ![88664-step1.png][1] Step2: Export the token via: https://learn.microsoft.com/en-us/azure/cognitive-services/custom-vision-service/copy-move-projects I use the online tool: https://westeurope.dev.cognitive.microsoft.com/docs/services/Custom_Vision_Training_3.3/operations/5eb0bcc6548b571998fddeb3/console - use the project id as project id - use the endpoint prefix as Resource Name - use the key as training key (That is right I think?) ![88648-step2a.png][2] [1]: /api/attachments/88664-step1.png?platform=QnA [2]: /api/attachments/88648-step2a.png?platform=QnA

Step 3: I copy the token (the string between the quotes) generated after clicking send ![88665-step3.png][1] Step 4: To import use the online tool: https://westeurope.dev.cognitive.microsoft.com/docs/services/Custom_Vision_Training_3.3/operations/5eb0bcc7548b571998fddee3/console further details: - New resource group created for it with new custom vision resource in it - Same domains - Name doesn’t has to be globally unique? - Like in step 1 I use the key and endpoint prefix but now from the target model ![88688-step4a.png][2] ![88691-step4b.png][3] [1]: /api/attachments/88665-step3.png?platform=QnA [2]: /api/attachments/88688-step4a.png?platform=QnA [3]: /api/attachments/88691-step4b.png?platform=QnA

anonymous user-8611 I was able to replicate your issue and I think this error is seen because the token parameter is a URL and this API console does not seem to support URL encoding for the param which is causing an invalid token error. I would request to use the curl option instead with the token for the import API and it should work as expected. Thanks for the details.

curl -v -G -X POST "{endpoint}/customvision/v3.3/Training/projects/import" --data-urlencode "token={token}" --data-urlencode "name={name}" -H "Training-key: {training key}" -H "Content-Length: 0"

Hello,
I have the same problem.
I trained an object detection model with images. I used two tags.

Then I removed one tag and tried to retrain it. The training was not possible. I added the Tag again and the training was sucessful.

Then I tried to move the project to another ressouce. First try it was not possible. A week later i tried again and it worked, but some iterations were missing.
I retrained the incompletely-moved model and deleted the original project.

Now i wanted to move the retrained model to still another ressource. When trying to export the model i get an error:
"Cannot export a project that has not been successfully created. Current project Status is: ImportingFailed."}* Connection #0 to host XXX left intact.

Is there a chance to fix it?

@Tom Jenkins Since you have deleted the original project and are planning to move the new project again I think the new project might be corrupted or needs to be checked from the backend on the error so you could re-train correctly. I would request to raise a support case for your current resource to have the service team look at the details. Thanks.
