The attribute with AttributeId = ‘guid’ was not found in the MetadataCache

I encountered this error when trying to export the solution from Dev environment. There was little information in the exception or the log file, but I could guess that something had been deleted and it didn’t update the MetadataCache (or the solution) somehow.

After googling, I found the solution is to delete the attribute/component from the CRM solution.

private static void RemoveComponentFromSolution(IOrganizationService service, Guid componentId, int componentType, string solutionName)
{
	RemoveSolutionComponentRequest removeRequest = new RemoveSolutionComponentRequest()
	{
		// this is the Guid you have found within your Dynamics 365 trace files
		ComponentId = componentId,
		ComponentType = componentType,
		// This is the unique name, not the display name of the solution you are trying to export
		SolutionUniqueName = solutionName
	};

	var response = service.Execute(removeRequest);
}

The component type can be retrieved using FetchXML

<fetch top="50" >
  <entity name="solutioncomponent" >
    <all-attributes/>
    <filter type="and" >
      <condition attribute="objectid" operator="eq" value="component guid here" />
    </filter>
  </entity>
</fetch>
