001055 : Cache storage format not supported.
Description
The specified cache storage format is invalid.
Solution
Specify the correct cache storage format. You see this error when you choose a format that is not supported by the operation. The user interface prevents this behavior, but you may see this error when you incorrectly type in an invalid format in scripting. For example, do not specify the source cache storage format while using the Convert Map Server Cache Storage Format tool.
