## Unsupported Authorization Type / Region Error (400)

The authorization type is not supported or configured incorrectly, which can result in an error such as `400`, often caused by issues with the processing region. To change your region in CloudConvert:

::::WorkflowBlock
:::WorkflowBlockItem
Navigate to the [CloudConvert dashboard](https://cloudconvert.com/dashboard).
:::

:::WorkflowBlockItem
In the left sidebar, click **Region**.
:::

:::WorkflowBlockItem
In the **Processing Region** section, select one of the specific servers instead of Auto.
:::

:::WorkflowBlockItem
Click **Update**.
:::
::::

For more information, refer to [CloudConvert Region Endpoints](https://cloudconvert.com/api/v2#overview).
:::::

The following errors may occur when using the **Convert a File** module:

## Output File Size Limit Exceeded

The output file size exceeds the limit allowed for your scenario. 

Please refer to file size limits in [Working with files](docId\:OAUIOo6OUjV0FYGlzMRte).

## Maximum Conversion Time Exceeded

The free CloudConvert plan offers 25 conversion minutes daily. If your usage exceeds the limit of the free plan, you may switch to [a (prepaid) package or subscription](https://cloudconvert.org/pricing).

## Invalid File Reference / Frame Size Error

Failed to read frame size: Could not seek to 1508. �/output/JLIADSA00137P0.mp3: Invalid argument.

This error is thrown e.g. when converting files from MP3 to WAV. Make sure that you have selected the correct region because it will find references to files but not only just the correct file.

## RunTimeError

Maximum number of repeats exceeded.

Locate the corresponding CloudConvert job in your [CloudConvert dashboard](https://cloudconvert.com/dashboard/jobs)'s list of jobs and check the job's duration:

::Image[]{src="https://api.archbee.com/api/optimize/oAyFj2GHlBeBVWF5OAir2/x_H1WL_rKqQPdr0rSnEA8_uuid-2049822e-b36f-b819-bdbe-9da93724a4b4.png" size="50" width="600" height="303" position="center" darkWidth="600" darkHeight="303" showCaption="false"}

The **CloudConvert > Convert a File **module's timeout is set to 3 minutes. If the job's duration exceeds 3 minutes (possibly due to a temporary overload of the CloudConvert service), the module throws the above mentioned error.

In this case consider one of these options:

- Enable the **[Allow storing of Incomplete Executions](docId\:evAR6qLowV4yyUnEyV-00)** option in the scenario settings to store the incomplete executions for later manual resolution. Optionally you may attach an error handling route to the **CloudConvert** module with the **Break** directive to resolve the incomplete executions automatically.Introduction to Error Handling
- Disable the *Download a file option* in the **CloudConvert > Convert a file** module. In this case the module will not wait for the conversion result. To obtain the conversion result, create a new scenario and use the **CloudConvert > New Job Event** trigger.
