dynamics crm - Set EntityReference attribute to not working Microsoft.Xrm.Data.PowerShell -


i cannot update theme powershell using microsoft.xrm.data.powershell.

the following code not working:

#get theme $res = get-crmrecords -conn $connection -entitylogicalname theme -filterattribute name -filteroperator eq -filtervalue $nameoftheme -fields themeid, name, logoid, isdefaulttheme, logotooltip, navbarbackgroundcolor, navbarshelfcolor, headercolor, globallinkcolor, selectedlinkeffect, hoverlinkeffect, processcontrolcolor, defaultentitycolor, defaultcustomentitycolor, controlshade, controlborder $importedtheme = $res.crmrecords[0]  #get resource web $reslogo = get-crmrecords -conn $connection -entitylogicalname webresource -filterattribute name -filteroperator eq -filtervalue "logoname"   $importedlogo = $reslogo.crmrecords[0]  $erlogo = (new-crmentityreference -entitylogicalname webresource -id $importedlogo.webresourceid)  #update theme $importedtheme.logoid = $erlogo  set-crmrecord -conn $connection -crmrecord $importedtheme

this given error:

 impossible d'appeler une méthode dans une expression null. au caractère c:\users\il...ll\microsoft.xrm.data.powershell.psm1:628 : 16 +             if($crmfieldvalue -eq $null) +                ~~~~~~~~~~~~~~~~~~~~~~~~     + categoryinfo          : invalidoperation : (:) [], runtimeexception     + fullyqualifiederrorid : invokemethodonnull  le cast spécifié n'est pas valide. au caractère c:\users\il...ll\microsoft.xrm.data.powershell.psm1:773 : 9 +         throw $conn.lastcrmexception +         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~     + categoryinfo          : operationstopped: (:) [], invalidcastexception     + fullyqualifiederrorid : le cast spécifié n'est pas valide.

i think problem comes verification in part of code of xrm.data.powershell:

if($crmfieldvalue -eq $null) {  write-host "$crmfieldvalue -eq $null"     $newfield.type = [microsoft.xrm.tooling.connector.crmfieldtype]::raw    $value = $null }

i cannot find solution. have idea?
