After publishing a print service with custom layouts from ArcGIS Pro 3.1.3 to ArcGIS Enterprise 11.1, I received the following error when trying to print:
Error executing tool. Export Web Map : ERROR 000820: The parameters need repair. ERROR 000800: The value is not a member of Portable Document Format (PDF) | 32-bit Portable Network Graphics (PNG32) | 8-bit Portable Network Graphics (PNG8) | Joint Photographic Experts Group (JPG) | Graphics Interchange Format (GIF) | Encapsulated PostScript (EPS) | Scalable Vector Graphics (SVG) | Compressed Scalable Vector Graphics (SVGZ) | Adobe Illustrator Exchange (AIX) | Tag Image File Format (TIFF). ERROR 000820: The parameters need repair.
The workaround solution is to use ArcGIS Pro 2.9.1 to publish a print service to ArcGIS Enterprise 11.1 until bugs are resolved.
The bug documented here implies that using ArcGIS Pro 3.x to publish a print service to ArcGIS Enterprise 11.1 will work, which is not what I'm experiencing.
@TomThompsonEsriCA tagging you to confirm that this is still an issue ArcGIS Enterprise 11.1 with a documented error message.
Nice find. Out of curiosity, was the problematic custom print layout originally created in Pro 2.9.x? If so, was it ever edited and saved in Pro 3.x?
Cheers,
