Hi!
I have a list in Sharepoint online.
When I want to edit the items in a grid view, i can't see all of my items.
In console I see the next message:
SPGrid FailToInitGanttControl: TypeError: Cannot read properties of null (reading 'display')
Could you help me what the problem is it?
I noticed, that one of my user doesn't have Work phone number in the field Work Mobile Number.
This field has a Person or Group type and show field as Work phone.
Additionally, I have added JSON formatting to this column.
{
"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
"elmType": "div",
"style": {
"box-sizing": "border-box",
"padding": "0 2px",
"overflow": "hidden",
"text-overflow": "ellipsis"
},
"attributes": {
"class": "sp-css-backgroundColor-BgMintGreen sp-css-borderColor-MintGreenFont sp-css-color-MintGreenFont sp-field-bold"
},
"txtContent": "[$Work_x0020_Mobile_x0020_Number.title]",
"defaultHoverField": "[$Work_x0020_Mobile_x0020_Number]"
}I tried to remove JSON from this column and it worked.
It’s strange why if there is no data in this field, JSON breaks it.
