Maximum Lookups for DFFS

[Jeff Lynch]

I have a list with a lot of lookups, and some of those were not being used however, SharePoint stopped working on all edit, new and display forms.

I contacted Microsoft and found that there was an error that basically said JSON length over 41000 bytes too large, we finally figured it out that each call to a lookup ads to the JSON call.

Is this limit a known issue or is there another way to minimize the data call when rendering a form with classic dffs?

I don’t think there is any other way than to reduce the number of fields. You can split a large list into multiple lists connected using vLookup (plugin to DFFS).
