After update to Node 10-alpine - ERR_STREAM_CANNOT_PIPE

[sashberd]

After I updated our server node JS to Node 10-alpine version I started to get next error

Error [ERR_STREAM_CANNOT_PIPE]: Cannot pipe, not readable.

I have to mention that with node 8-alpine this code is working (I tried with rollback)

In my code I am trying to return file from GCloud:

try {
        const file = await 
         gcs.bucket(`BUCKET_NAME`).file(filePath);

        if (file) {
            const results = await file.getMetadata();
            const stream = await file.createReadStream();
            return res.pipe(stream);
            else {
                return send(res, 403)
            }
        }
        else {
            return send(res, 404);
        }
    } catch (err) {
        console.error(err);
        return send(res, 500);
    }

Is any one met such issue after upgrade to node -10 -alpine?

@sashberd - yes, piping of outgoing message (in this case res.pipe) is inhibited through #14358, and this change is in effect from Node 10.

Hope this helps.

@gireeshpunathil Thanks. May be you know workaround?

[gireeshpunathil]

yes - stream.pipe(res) - !!!

[gireeshpunathil]

in this context, the correct definition of pipe is: connect the receiver object's read descriptor into the input object's write descriptor, not vice versa. receiver object is the file stream, and the input object is the server response, a Writablestream.
