How to send an array of pdf files using form-data #553
Description
I'm trying to send an array of pdf files to backend using form-data lib
I was trying to append pdf files like this:
const formData = new FormData();
for (const file of files) {
formData.append('file[]', fs.createReadStream(file.path), {
filename: `${file.type}_${file.month}.pdf`,
});
}
and this is the axios request
Axios.request({
method: 'POST',
url,
headers: {
'Content-Type': data.formData.getHeaders()['content-type'],
},
data: data.formData,
});
but I'm getting this error, everytime I make an axios request
node_modules/express/lib/response.js:1150
: JSON.stringify(value);
^
TypeError: Converting circular structure to JSON
--> starting at object with constructor 'Object'
| property 'curlObject' -> object with constructor 'CurlHelper'
--- property 'request' closes the circle
at JSON.stringify (<anonymous>)
can anyone please tell me what's the issue here?

I would say that you don't need this pkg anymore.
fetch, blob and formdata is built in globally now.

@jimmywarting I am getting
Cannot find name 'FormData'.compilation error from TypeScript using Node 18.16.1, is there something I need to configure to let TypeScript aware of this global?jimmywarting commentedon Sep 6, 2023
if you are going to use
fs.openAsBlob(path[, options])then you will need v19.8+maybe try to install latest @types/node

@jimmywarting Should have clarified that I am not using
openAsBlob, the issue is strictly related to the first lineconst formData = new FormData(). And I have the latest@types/node. :(jimmywarting commentedon Sep 6, 2023
Built in
FormDatais not going to accept a readableStream... if that is what you are using. saw you where usingfs.createReadStream(file.path)sry, can't help you there.
