Hello @loudmu

Welcome to the Prismic community, and thanks for reaching out to us.

All slices come under body object by default. You have to mention body object too to retrieve the Slices. So, your query should look like this:

const menuQuery= { menuDemo { body { ...on menu_links { non-repeat { ...non-repeatFields } } } } }

Find more details in our graphQuery article.

Thanks,
Priyanka

thank you for your fast answer,but unfortunately it doesn't work
the message is;

Server Error
Error: Unable to parse fetch query Invalid fetch parsing Exception.

Invalid input ' ', expected '\r' or '\n' (line 1, column 2):
{ menuDemo { body { ...on menu_links { non-repeat { ...non-repeatFields } } } } }
 ^

2 rules mismatched at error location:
  /InputLine/ /Docs/ /bracketed/ /NewLine/ ? / '\r'
  /InputLine/ /Docs/ /bracketed/ /NewLine/ '\n'

when I query menudemo without the graphQuery the response is
