JS API 4.15: Custom Print template issue

[shaileshgavathe]

Hello,

Not sure, how to fix this one particular issue. 

Published the custom print python tool for the Custom Layout (pagx) files by following the guidelines https://enterprise.arcgis.com/en/server/latest/create-web-apps/windows/tutorial-publishing-additiona...

Able to see the new Template options under Print Tool, but when we try it to print it, it gives the below error.

[esri.core.Accessor] Accessor#set 'Custom_Quicklook_Template_11x17_105' is not a valid value for this property, only the following values are valid: 'map-only', 'a3-landscape', 'a3-portrait', 'a4-landscape', 'a4-portrait', 'letter-ansi-a-landscape', 'letter-ansi-a-portrait', 'tabloid-ansi-b-landscape', 'tabloid-ansi-b-portrait'

Then added the extend to the TemplateOptions from Accessor but the error still exist.

export interface TemplateOptions extends __esri.Accessor {

    layout:

    | "map-only"

    | "a3-landscape"

    | "a3-portrait"

    | "a4-landscape"

    | "a4-portrait"

    | "letter-ansi-a-landscape"

    | "letter-ansi-a-portrait"

    | "tabloid-ansi-b-landscape"

    | "tabloid-ansi-b-portrait"

    | "Custom_Quicklook_Template_11x17_105";

    /**

    * When `false`, the legend is not displayed on the printout.

}

Thanks and Regards,

What version of the API is this? I think this error happened a couple of versions ago, but has since been fixed.

Never mind, version in title. This is fixed in 4.16 and above.

Thanks ReneRubalCava.  Upgraded to 4.17. Unfortunately the Error still exist?

Used below packages

   "@arcgis/webpack-plugin": "4.17.5",

   "@types/arcgis-js-api": "4.17.0",

Found the workaround by Intercepting the request with esriConfig.

             if(esriConfig){                    

                    esriConfig?.request?.interceptors?.push({

                        // set the `urls` property to the URL of the print service so that this

                        // interceptor only applies to requests made to the print service URL

                        before: function(params) {

                            if (params.url.includes("Print")) {

                                params.requestOptions.query.Layout_Template = "customtemplate";                                  

                            }

                        }

                    });

                }
