For our Zapier app at Placid.app we use fields with children (line items) to structure our form better. Depending on the users template it can get really huge!
f.ex.:

The problem we encounter is that when using a file input and sending in a file we get this error:

With file, I mean a hydrated string starting with “HYDRATE|||”
I assume this is a JS error on Zapier’s end, with a file being nested in this field[children] construct. Is there anything I can do to fix that? I’m on the CLI and it seems that I cannot touch that data before Zapier tries to JSON parse it
Any help would be appreciated!
