Dynamics 365 Error #2 Object reference not set to an instance of an object

By -

As Microsoft Dynamics developer, We came across this error regularly in our day to day life.

Problem Description:-  "Object reference not set to an instance of an object"

There could be multiple reason we come across this issue. However below are few things which can be looked at to fix this issue and save your time.

  • Entity Attribute/Field does not contains data or the value is null. Say you are trying to get FirstName from Lead Entity attribute and splitting the value into two string based on some parameter.

    string[] strArray=objLead["firstname"].split(',');

    This particulat line of code will throw Object Reference error if FirstName is null. To avoid this, We can add check condition as below.

    if(objLead.Attributes.Contains(firstname) && objLead["firstname"]!=null);
    string[] strArray=objLead["firstname"].split(',');

    Other way to fix this is to use objLead.GetAttributeValue<string>("firstname"); Then check for null.

    Hope this will help!

Why Failure Is Good for Success

The sweetest victory is the one that’s most difficult. The one that requires you to reach down deep inside, to fight with everything you’ve got, to be willing to leave everything out there on the battlefield—without knowing, until that do-or-die moment, if your heroic effort will be enough. Society doesn’t reward defeat, and you won’t find many failures documented in history books. The exceptions are those failures that become steppingstones to later success. Such is the case with Thomas Edison, whose most memorable invention was the light bulb, which purportedly took him 1,000 tries before he developed a successful prototype. “How did it feel to fail 1,000 times?” a reporter asked. “I didn’t fail 1,000 times,” Edison responded. “The light bulb was an invention with 1,000 steps.” Unlike Edison, many of us avoid the prospect of failure. In fact, we’re so focused on not failing that we don’t aim for success, settling instead for a life of mediocrity. When we do make misste...
