If you are notified on the adapter details page that training has failed, refer to the status message to understand the error and correct it. There are two types of errors: creation errors and file errors. Some status messages are returned in the console, while others are displayed in a validation file.
The validation file that is created alongside a training job contains information on
the types of errors encountered when training. If the error message states that the
error is a validation error ("Status message = Manifest file contains invalid records.
Consult validation error file at OutputConfig path for more details."), refer to the
validation file located in the S3 output bucket you chose during adapter training. The
generated validation file is named validation_errors.jsonl. Each line in
the file corresponds to a line in the manifest file, with errors yielded for each line
in the manifest file that produces an error.
The following is a list of all creation errors and possible causes:
| Error name | Error description |
| CREATION_ERROR | Manifest file contains invalid records. Consult validation error file at OutputConfig path for more details. |

To see API error descriptions, see the Amazon Textract API Reference for the appropriate operation. If an error occurs when you try to create a new adapter with the CreateAdapterVersion operation, see the API Reference page. If an error occurs when using the Amazon Textract console, read the error pop-up for information on why the operation failed.
