node response is missing

I am trying to trouble shoot/fix my nodejs upload image api:

My service is being stuck at somewhere.

My service is too simple, just uploading the image by resizing through sharp api in a directory and return the full path of that file.

When I select some image at first time then everything works fine and image upload successfully with a response

but When I try to crop that image after clicking on the image and try to save it (at second time) then nodejs service return following response.

I don't why it is being happened, I tried to debug the service code and It didn't stop at anywhere. Flow has been passed/executed successfully, I didn't catch any exception/error in code.

What can be the issue in it because it still displaying

Blockquote failed to load response data. no resource with given identifier found
Problem area is in the code of onSaveImage when a server side call is being served/requested. I am using the plugin for image cropping is react-easy-crop. Browser is getting refresh/reload at this line of code

const jsonRes = await responseMain.json();
I am sharing my nodejs service code as well as reactjs code. please look into it. Thank you.

and following is my reactjs code.

const settings = {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
filename: filename,
image: base64Image,
}),
};
setLoader(true);
let submitUrl = process.env.REACT_APP_SERVER_DOMAIN +/uploaddetail;
const responseMain = await fetch(submitUrl, settings);
const jsonRes = await responseMain.json();

Anyone can share his thoughts on it ?
thank you
