CauseCheck if a custom processor was created with the sys_id, id or table as parameter. Based on the documentation below, custom processor are deprecated. Instead, the Scripted REST APIs should be used:Processors In addition, processors cannot have as parameters sys_id since this breaks functionality in the Platform.From the documentation: "Parameter names must be processor-specific. Do not choose common parameter names that another processor might use. If you use a common parameter name, such as id, sys_id or table in a processor, it can break other functionality, since the processor wins when that parameter exists in a URL. For example, a processor with an id parameter, regardless of the Path value in the same record, breaks the Service Portal, which depends on that parameter for page identification."
