SSRS 2017 configuration

I tried to add another option to export report in CSV but replace coma(,) with pipe (|) delimiter. My report server 2017. I modified rsreportserver configuration file and added this code:

<Extension Name="Pipe" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering"/><OverrideNames><Name Language="en-US">Pipe</Name></OverrideNames><Configuration><DeviceInfo><Encoding>ASCII</Encoding><FieldDelimiter>&vert;</FieldDelimiter><UseFormattedValues>False</UseFormattedValues><NoHeader>False</NoHeader><FileExtension>csv</FileExtension></DeviceInfo></Configuration></Extension>

After the server stop working.

Any help will be appreciated.

Thank you
