5XX	Internal server error Service unavailable	None	Any	Our systems encountered and logged an unexpected error. Please contact us if you continue to see the error.

Error codes that can occur when you access datasets, labels, or examples.

HTTP Code	HTTP Message	API Message	Resource	Possible Causes
400	Bad Request	None	Any dataset, label, or example resources.	The request couldn’t be fulfilled because the HTTP request was malformed, the Content Type was incorrect, there were missing parameters, or a parameter was provided with an invalid value.
400	Bad Request	The name parameter is required to create a dataset.	POST /vision/datasets	The name parameter was passed in, but no value was provided.
400	Bad Request	Uploading a dataset requires either the data field or the path field.	POST /vision/datasets/upload	The path to the local .zip file or the URL to the .zip file in the cloud wasn’t specified.
400	Bad Request	The data parameter cannot be duplicated, nor sent along with the path parameter.	POST /vision/datasets/upload	Both the path and data parameters were passed to the call; only one of these parameters can be passed.
400	Bad Request	The dataset is not yet available for update, try again once the dataset is ready.	PUT /vision/datasets/<DATASET_ID>/upload	You’re adding examples to a dataset that’s currently being created. You must wait for dataset to become available before you can add examples to it.
400	Bad Request	Failed to download the dataset from the public URL.	POST /vision/datasets/upload/ vision/datasets/upload/sync	The API can't access the dataset file via the URL provided. When specifying the URL for a .zip file in a cloud drive service like Dropbox, be sure it's a link to the file and not a link to the interactive download page. For example, the URL should look like https://www.dropbox.com/s/abcdxyz/mountainvsbeach.zip?dl=1.
400	Bad Request	Supported dataset types: [image, image-detection, image-multi-label]	POST /vision/datasets/upload	The type request parameter contains a value that isn't a valid dataset type.
400	Bad Request	Example max size supported is 1024000.	POST /vision/datasets/<DATASET_ID>/examples	The image file being added as an example exceeds the maximum file size of 1 MB.
404	Not Found	None	Any dataset, label, or example resources.	The requested REST resource doesn’t exist or you don't have permission to access the resource.
404	Not Found	Unable to find dataset.	GET /vision/datasets/<DATASET_ID>	You don't have access to the dataset. The dataset was deleted.
404	Not Found	Unable to find dataset.	DELETE /vision/datasets/<DATASET_ID>	You don't have access to the dataset. The dataset was deleted.
404	Bad Request	Example file already exists for the label <NAME_OF_EXAMPLE>.	POST /vision/feedback	An example with the same name already exists in the dataset. Example names must be unique within a dataset.
404	Bad Request	Duplicate labels are not allowed.	POST /vision/datasets	The call is trying to create a label with a name that exists in the dataset. Label names must be unique within a dataset.
503	Service Unavailable	Operation timed out!	GET /vision/datasets	The call has timed out due to large data size. By default, this call returns 25 datasets. If the datasets contain a lot of examples, this call may time out. Use the offset and count parameters to limit and page through the data.

Error codes that can occur when you train a dataset to create a model or access a model.

HTTP Code	HTTP Message	API Message	Resource	Possible Causes
400	Bad Request	The name parameter is required to train. A valid datasetId parameter is required to create a example.	POST /vision/train	The name or datasetId parameter was passed in, but no parameter value was provided.
400	Bad Request	The name or datasedId parameters are required to train.	POST /vision/train	The name or datasetId parameter is missing.
400	Bad Request	Invalid id <MODEL_ID>	GET /vision/train/<MODEL_ID>	There’s no model with an ID that matches the modelId parameter.
400	Bad Request	Invalid id <MODEL_ID>	GET /vision/train/<MODEL_ID>/lc	There’s no model with an ID that matches the modelId parameter.
400	Bad Request	The job has not terminated yet; its current status is RUNNING. The job has not terminated yet; its current status is QUEUED.	GET /vision/models/<MODEL_ID>	The model for which you are getting metrics hasn’t completed training.
404	Not Found	None	GET /vision/models/<MODEL_ID>	The modelId parameter is missing.
405	Method Not Allowed	None	GET /vision/train/<MODEL_ID>	The modelId parameter is missing.

Error codes that can occur when you make a prediction.

HTTP Code	HTTP Message	API Message	Resource	Possible Causes
400	Bad Request	None	POST /vision/predict	The prediction request couldn’t be fulfilled because the HTTP request was malformed, the Content Type was incorrect, there were missing parameters, or a parameter was provided with an invalid value.
400	Bad Request	Bad Request: Bad sampleLocation	POST /vision/predict	The URL passed in the sampleLocation parameter is invalid. The URL could be incorrect, contain the wrong file name, or the file may have been moved.
400	Bad Request	The modelId parameter is required.	POST /vision/predict	The modelId parameter is missing.
400	Bad Request	Bad Request: Missing sampleLocation, sampleBase64Content, and sampleContent	POST /vision/predict	The parameter that specifies the image to predict is missing.
400	Bad Request	File size limit exceeded	POST /vision/predict	The file you passed in for prediction exceeds the maximum file size limit of 5 MB.
400	Bad Request	Bad Request: Unsupported sample file format	POST /vision/predict	The file you passed in for prediction isn’t one of the supported file types.
403	Forbidden	Forbidden!	POST /vision/predict	The model specified by the modelId parameter doesn’t exist. The modelId parameter was passed in but no value was provided.
429	Too Many Requests	You've reached the maximum number of predictions.	POST /vision/predict	You have exceeded the number of prediction requests for your current plan. Contact your AE to update your plan. See Rate Limits.
