Script Error received when saving Purchase Order... Cannot read property 'length' of undefined

Posted on by admin4media 15

Hello Everyone, 

I have am receiving a script error when saving a Purchase order in Dynamics 365. I reported the issue and shared the error with Microsoft. They advised me that there is custom code in our form, that is unsupported by the break-fix team. I have only used the API customization in advanced options. 

Can anyone advise what the error may be caused by, and how to fix it? The log file is pasted below. 

TypeError: Cannot read property 'length' of undefined

    Hello,

    Looks like this is the customization related to Dynamics 365 customer engagement but this forum is for Dynamics 365 for finance and operations.

    Could you please repost in the customer engagement forum to get a swift support.

    Thanks

    Hi admin4media,

    As the log suggests , you are checking length of a variable which is either undefined or null , add debugger on the PurchaseOrder javascript and check where you're getting the error. If possible share the custom code written in PurchaseOrder.js and we can help. Also please mask the organization name while sharing the log in future. i.e 4media-group shouldn't be visible.
