Answer 1

The error indicates that Sitecore is trying to use a computed index field (PdfComputedField) defined in the class Suncor.Sitecore.PCL.Search.Helpers.PdfComputedField from the assembly Suncor.Sitecore.PCL.Search, but it cannot locate the type or assembly.

Here’s how you can troubleshoot and resolve the issue:

1. Verify Assembly Presence Check the bin folder of your Sitecore instance to ensure the Suncor.Sitecore.PCL.Search.dll assembly is present. If the assembly is missing: Obtain it from your source control or build it from your solution. Deploy it to the bin folder of your Sitecore instance.

2. Validate Assembly Configuration Open the App_Config folder and locate the configuration file where the PdfComputedField is referenced. Confirm that the fully qualified name of the computed field matches the class and namespace in the Suncor.Sitecore.PCL.Search assembly.
