Hello!!
I have to make an update to our website, meant to go live tomorrow and it’s giving me a deployment error when I try to publish.
The site is attached to Contentful for content management and when I made the changes through there, I am getting a notice of “Failure During Install Dependencies.”
Any help you can provide would be amazing!
I should also preface this with saying that I know NOTHING about coding or any of this. It’s a different language to me.
ANY HELP WOULD BE SO APPRECIATED AS I’M UNDER A TIGHT DEADLINE!!
Thank you so much!!!

Below is the Error message and AI “solution” I am getting on Netlify:
line 82: The error AttributeError: module ‘collections’ has no attribute ‘MutableSet’ indicates that the collections module being used does not have MutableSet.

Solution
This error is likely due to a Node version mismatch. The module collections.MutableSet was added in Node.js version 12.0.0 and the current Node version being used is 10.19.0. To resolve this issue, you need to update the Node version to at least 12.x.

To change the Node.js version in your Netlify build, you can refer to the documentation on changing Node versions. After updating the Node version, run the build again to ensure that the collections.MutableSet error is resolved.

Unfortunately, you’re using severly outdated pieces of software in your site. Gatsby v2 has long reached its End of Life and we don’t support it anymore. It might work, but if it doesn’t (llike in your case), we don’t provide any technical support. You’re in dire need of upgrading your site’s codebase to newer versions.

Thank you for responding! Do you know who could do this? or can you point me in the direction of a company who can? I don’t know anything about this.

Your best bet is to hire a developer who can do this - I doubt you’d make it in time for your deadline though.

@LFFip I cannot see your build log as I do not work for Netlify.

The documentation for managing the Node.js version on Netlify is here:
