Metadata Binding Error Codes

NOTE

This topic describes only module-specific error codes. For details about universal error codes, see Universal Error Codes.

32100001 File Creation Failed

Error Message Internal handling failed. File creation failed.

Symptom This error code is reported if a service error occurs when a certain metadataBinding API called.

Possible Cause The service is abnormal.

Solution 1. Retry the operation at a specified interval (for example, 1s) or at an exponential increase interval. 2. If the operation fails for three consecutive retries, return the original image.

32100002 Encoding Failed

Error Message Encoding failed. Possible causes: 1. Image processing error; 2. Channel coding error.

Symptom This error code is reported if the encodeImage API fails because of an algorithm error.

Possible Cause Algorithm execution fails because of memory allocation failures or other reasons.

Procedure 1. Retry the operation at a specified interval (for example, 1s) or at an exponential increase interval. 2. If the operation fails for three consecutive retries, return the original image.

32100003 Decoding Failed

Error Code Information Decoding failed. Possible causes: 1. Image not encoded; 2. Image destroyed.

Symptom This error code is reported if the decodeImage API fails because of an algorithm error.

Possible Cause Algorithm execution fails because of memory allocation failures or other reasons.

Procedure 1. Retry the operation at a specified interval (for example, 1s) or at an exponential increase interval. 2. If the operation fails for three consecutive retries, return an empty link.

32100004 Subscription Failed

Error Code Information Subscription failed. Possible causes: 1. Abnormal system capability; 2. IPC exception; 3. Algorithm loading exception.

Symptom This error code is reported if subscription fails when the on API of the metadataBinding module is called.

Possible Cause Subscription to change events has failed.

Procedure 1. Retry the operation at a specified interval (for example, 1s) or at an exponential increase interval. 2. If the operation fails for three consecutive times, stop the retry.

32100005 Unsubscription Failed

Error Code Information Unsubscription failed. Possible causes: 1. Abnormal system capability; 2. IPC exception.

Symptom This error code is reported if unsubscription fails when the off API of the metadataBinding module is called.

Possible Cause Unsubscription from change events has failed.

Solution 1. Retry the operation at a specified interval (for example, 1s) or at an exponential increase interval. 2. If the operation fails for three consecutive times, stop the retry.
