XMLHttpRequest error

[huongtran84]

when I run my web flutter in debug mode ,Meilisearch is good working, but when I deploy web on firebase hosting ,throw exception

MeiliSearchApiError - message: XmlHttprequest error .I guess due to Cors policy ,

MeiliSearch live in DigitalOcean server
I modified firebase.json to:
{ "functions": { "source": "functions" }, "hosting": { "public": "build/web", "ignore": [ "firebase.json", "**/.*", "**/node_modules/**" ], "headers": [ { "source": "*", "headers": [ { "key": "Access-Control-Allow-Origin", "value": "*" } ] } ] } }
I also did implement Reverse Proxy
but it did not help

here log:

Hi @huongtran84

Sorry for the inconvenience. I might be wrong but It seems like a common problem with the flutter web. Have you considered disabling web security as indicated in this answer?

Let me know if that resolves the issue. Thanks.

after I modified config file with added domain name, and HTTPS. It is resolved
