Caused by: java.io.UnsupportedEncodingException

This exception occurs when the character encoding used to convert a string into bytes is not supported by the system. For example, if the string is encoded in a non-standard character set, or if the system does not have the necessary libraries to support a particular character encoding, this exception may be thrown.

To resolve this issue, you can try using a different character encoding that is supported by the system. You can also update the system's libraries to include support for the required encoding. Additionally, you may need to modify the code that is causing the exception to use a different method for encoding the string.
