I have a little problem and I need your help to help me solve it. .

How the error is occurring:

Basically it is occurring, when I click on a button to open a modal to bring the information I want within this listing, however this "Occurrences", is necessary for other modals (front screens), I am using it to take advantage and catch the idCarregamento, for me to make the comparison and bring the information.

I know that there is firstordefault(); however I believe it is this way because I am wanting 1 information

  • This error usually occurs because there is some variable with null reference in a lambda expression, check the model (Occurrencedatamodel model), it is null??

  • Champion checks if the model or model.idThe current is null. I had a mistake like this and the reply of the friend Adimar solved for me, it was something within the expression that was null.

Usually this error occurs when some object of your expression is null.

Make a check before to know if this ctx.tb_occurrence is null, only after making sure you actually make your select.
