Please give me some advice. If there’s any information that I couldn’t provide, please leave a comment. thank all .
Hey!
What does it look like if you run the app locally?
Do you have that set differently in the app elsewhere?
There was no problem when running in a local environment. (CORS issue not present)
Luckily, my team found possible error in fly.io, and fix Like this. successful. Now it’s work!
const frontUrl = process.env.FRONT_URL || "https://SOMTHING.netlify.app";
apiRouter.use("/", cors({ origin: frontUrl }));
I’m so grateful that you even replied. Thank you very much for your interest in my problem.
Have a good day. jphenow !!
