I'm facing this error when I try to read the metadata of a permission set with version 42 of the api, I can't find what you may be missing and I can't identify how to solve it
these are the classes :
public class PermissionSet extends Metadata {
public String type = 'PermissionSet';
public String fullName;
private String[] fullName_type_info = new String[]{'fullName',SOAP_M_URI,null,'0','1','false'};
public StrongpointMdtServ.PermissionSetApplicationVisibility[] applicationVisibilities;
public StrongpointMdtServ.PermissionSetApexClassAccess[] classAccesses;
public StrongpointMdtServ.PermissionSetCustomPermissions[] customPermissions;
public String description;
public StrongpointMdtServ.PermissionSetExternalDataSourceAccess[] externalDataSourceAccesses;
public StrongpointMdtServ.PermissionSetFieldPermissions[] fieldPermissions;
public Boolean hasActivationRequired;
public String label;

public StrongpointMdtServ.PermissionSetApexPageAccess[] pageAccesses;
public StrongpointMdtServ.PermissionSetRecordTypeVisibility[] recordTypeVisibilities;

public StrongpointMdtServ.PermissionSetUserPermission[] userPermissions;
private String[] applicationVisibilities_type_info = new String[]{'applicationVisibilities',SOAP_M_URI,null,'0','-1','false'};
private String[] classAccesses_type_info = new String[]{'classAccesses',SOAP_M_URI,null,'0','-1','false'};
