I’m trying to re-use a function I already deployed in a new app. When testing on
localhost I encounter CORS issues (as one would ), so I tried adding
headers to the
netlify.toml of the original app:
[build] functions = "./functions" command = "yarn run build" publish = "public" [[redirects]] from = "/feedback" to = "/.netlify/functions/feedback" status = 200 [[headers]] # Define which paths this specific [[headers]] block will cover. for = "/feedback" [headers.values] Access-Control-Allow-Origin = "*"
However, I can verify that while the app still works, the
Access-Control-Allow-Origin is not returned (tried calling it with Postman: results came back, header didn’t). I tried adding several other headers to test, even tried
for = "/*" - to no avail.
What am I missing? How can I return the proper CORS header for my function?
