Solutions

1. Check the property key's expected type and provide a value of that type.
2. Remove surrounding whitespace or quotes that prevent the value from being parsed.
3. Consult the documentation for the valid value range or format of the property.

When it happens

Trigger: A ShardingSphere property value cannot be converted to the typed value declared for its key in TypedPropertyValue.

Common situations: Non-numeric text given for an integer property, or an unrecognized literal for a boolean property in the configuration.
