Following is a row from my bulk update http body  
When i run the same for small set of records (100) the same works fine but if i trigger the for the entire DB the the valueTimestamp field always null where other values are updated fine.

{"update" :{"\_index":"masterdata","\_type":"\_doc","\_id":"6.50"}}  
{"script" : {"lang":"painless","source": "if (!ctx.\_source.containsKey("assignedAttributes") &&  
params.assignedAttributes != null && params.assignedAttributes.attributeId != null )  
{ctx.\_source["assignedAttributes"] = new ArrayList(); }  
if( params.assignedAttributes != null && params.assignedAttributes.attributeId != null )  
{ int num = -1; for (int i =0; i = ctx.\_source.assignedAttributes.size(); i++)  
{ if (ctx.\_source.assignedAttributes.get(i).attributeId != null && ctx.\_source.assignedAttributes.get(i).attributeId == params.assignedAttributes.attributeId )  
{ num= i; break; } } if (num == -1)  
{ ctx.\_source.assignedAttributes.add(params.assignedAttributes); return; }  
else { ctx.\_source.assignedAttributes.set(num, params.assignedAttributes); } }  
if(!ctx.\_source.containsKey("assignedAttributes"))  
{ ctx.\_source.assignedAttributes = params.assignedAttributes; }","params":{"companyId":6,"customerId":50,"assignedAttributes":{"customerAttributeId":20391484,"attributeId":220,"valueDataType":"timestamp","valueTimestamp":["2021-02-09"]}}}}
