Error running `jss deploy app`: TypeError: logReplies.forEach is not a function

Question

When running:

jss deploy app --includeContent --includeDictionary --acceptCertificate XX:XX:XX:XX:XX:XX...

I get the error:

Sitecore has accepted import task JSSImport-myapp-2:59:34 PM
Unexpected error processing reply from import status service: TypeError: logReplies.forEach is not a function

I have verified:

• Local Sitecore 10.1 instance is working correctly
• JSS (16.0.0) packages installed to Sitecore instance (Also using SXA)
• Using JSS CLI 16.0.0
• Correctly and successfully ran jss setup and jss deploy config
• Restarted machine

Existing JSS repo in React that works on over devs local environments.

But:

Looking in the log files everything looks good and the deploy worked! (Even though the shell errors out)

I have got the same error for the Sitecore 10.x version. I have followed the below steps to resolve the error:

1. Uninstall npm Sitecore JSS in global and local path(where your code placed)

    npm uninstall -g @sitecore-jss/sitecore-jss-cli
    npm uninstall -i @sitecore-jss/sitecore-jss-cli

2. Again install the Sitecore JSS package.

    npm install -g @sitecore-jss/[email protected]
    npm install -i @sitecore-jss/[email protected]

The version mentioned should match with the installed packages Sitecore Headless Services Server for Sitecore 10.1.0 XM 16.0.0 rev. 210223.zip.

Answer 2

The global jss cli version on the machine was correctly 16.0.0, meanwhile the jss cli version declared in the project's package.json was 15.x.x, updating the package.json to ^16.0.0 and and a fresh npm i seemed to do the trick!

Answer 3

When creating a new JSS app and if the JSS app is based on a particular version, I had to specify the JSS GitHub branch name from where the template should be used. The error did not happen when I tried to deploy the app in Sitecore.

For JSS 15.0.1, I used the branch name release/15.0.0.

jss create testapp react --branch release/15.0.0
