Error In SDK

Hi,

Ian using connectwise .Net SDK 2017.2 and .Net SDK 2018.2.

When am calling a Method  GetCatalog(conditions: "Identifier = 'XYZ#ABA'") of CatalogsItemApi ,in condition am passing a Identifier name,In some cases my Identifier  name contains special character like #,& etc,that time this method gives 400 Error but if with the same Identifier i call to CreateCatalog() method it create the catalog item with Identifier contains special character.

Please suggest me a solution that how can i call  Method  GetCatalog() with Identifier contains special character,

I also tried the HTML Encode.

Thanks In Advance.
