Hi All, We’re looking to create a custom object by creating a new schema on the CRM custom objects page for the developer resource. We are receiving an error code called “Invalid primary display property: my\_object\_property” (screenshot attached). We can’t figure out what this is relating back to. Does anybody have experience with this or know what might be causing this? Thanks ![39372i9D3D96FBA03B8BE0.jpg](https://d2qpr2jzcazej7.cloudfront.net/original/3X/f/9/f9542f2f39cff39eef315e47756ab12d23b753f0.jpeg) ---

Hi @JHodgson Probably the solution… Click the see all params button at the bottom of the entry: ![39453i18EAF48CA06D3813.jpg](https://d2qpr2jzcazej7.cloudfront.net/original/2X/2/25c3096a1607c7e2a7f9d7c97d8d0108d9456730.jpeg) And it will reveal the primary display property, probably with the default value in place: ![39455i95FDF99047A11F12.jpg](https://d2qpr2jzcazej7.cloudfront.net/original/3X/7/9/797d56471b1cdc32e3f5130b05fdd6eb8c7382c7.jpeg) Let me know if this is it?
