I have Sitecore 9.3 version and followed the steps described here https://jss.sitecore.com/docs/getting-started/jss-server-install to setup JSS server. I am not able to deploy the app while running deploy command, I am receiving the error

Unexpected error processing reply from import status service:
TypeError: Cannot read property 'forEach' of undefined
at C:\jss\jss-app\node_modules\@sitecore-jss\sitecore-jss-dev-tools\dist\package-deploy.js:238:42 at processTicksAndRejections (internal/process/task_queues.js:93:5)

Anyone know how to solve this issue. Thanks in advance.


This issue can happen due to incompatible version of JSS app with sitecore version. Can you verify what version you have used when creating your jss app?

For sitecore 9.3 you need to create jss app using release/13.0.0 by this syntax: jss create appname react -b release/13.0.0. You can verify the JSS module compatibility with the sitecore version on the page https://kb.sitecore.net/articles/541788


Also make sure both your global jss cli version and the jss cli version in your project's package.json match!

I had this same error: Error running `jss deploy app`: TypeError: logReplies.forEach is not a function
