The ERR_STREAM_DESTROYED
error you're encountering typically indicates an attempt to perform operations on a stream that has already been closed or destroyed. This can happen if your code tries to write to or close a stream that's not in a valid state, often due to asynchronous operations not being managed correctly.
To address this, ensure that your asynchronous operations, especially those involving the printer, are properly sequenced and that you're not attempting to use the printer before it's ready or after it's been closed. Wrapping your printing logic in a Promise and using async/await can help manage these operations more predictively.
Here's a more reliable approach to handle printing asynchronously:
const print = (text) => {
return new Promise((resolve, reject) => {
device.open(function (error) {
if (error) {
return reject(error);
}
printer
.font('a')
.align('ct')
.style('bu')
.size(1, 1)
.text(text)
.cut()
.close(() => {
resolve();
});
});
});
};
In this setup, the print
function is wrapped in a Promise, ensuring that the device is opened successfully before attempting to print. This method helps in managing the stream's lifecycle more effectively, reducing the likelihood of encountering ERR_STREAM_DESTROYED
errors.
Additionally, verify that all libraries, especially escpos
and its dependencies, are compatible with your Node.js version (v20.11.0). Incompatibilities between Node.js versions and libraries can lead to unexpected errors, including those related to stream and network issues.
Implementing these suggestions should help mitigate the issues you're experiencing by ensuring proper stream management and asynchronous operation handling. If the problem persists, checking for library compatibility with your Node.js version and ensuring that your asynchronous logic is correctly structured will be crucial steps in troubleshooting further.
`Hi! I'm getting an error that seemingly came out of nowhere, as it didn't happen during my testing phase, but did happen during my production phase.
When trying to print a receipt using my below code: `app.post('/create/order', async (req, res) => { // we're getting an order! let's print it! console.log("printing order with id: #" + req.body.orderId) console.log(req.body) let foodString = ""; let drinksString = ""; let dessertsString = "";
})
I get the following error:
Error [ERR_STREAM_DESTROYED] Cannot call write after a stream was destroyed` See pictures below for full error:Is there an issue with my code, is it my Node version? (v20.11.0) I can't seem to get it working.
