Description

I'm using the esm build version 5.5.0 of csv-parser with Vite, and I'm encountering the following error in the browser console:

Uncaught TypeError: "listener" argument must be a function
_addListener index.js:2161
addListener index.js:2222
on index.js:4057
err index.js:6457
parse index.js:5961
_transform index.js:6453
_read index.js:4993
_write index.js:4981
doWrite index.js:4600
writeOrBuffer index.js:4589
write index.js:4527
writer index.js:6519

For some reason, this.destroy is undefined. Everything seems to work, but how can I address this error message?

Despite the error, the functionality appears to be intact. What steps can I take to resolve or mitigate this issue?

Research direction

Reproduce the issue with csv-parser 5.5.0's ESM build in Vite and inspect the browser stack trace around index.js, especially the parse and err paths. Compare the stream behavior in the Vite browser bundle with the Node environment, then verify that CSV parsing completes without the listener error.
