Build ERROR opt/build/repo/.cache/loader.js: Missing class properties transform

PLEASE help us help you by writing a good post!

  • we need to know your netlify site name. Example: gifted-antelope-58b104.netlify.app
    https://60458abd35012400073438dd--zealous-neumann-40b351.netlify.app/

  • DNS issues? Tell us the custom domain, tell us the error message! We can’t help if we don’t know your domain.

  • Build problems? Link or paste the FULL build log & build settings screenshot

The better the post - the faster the answer.

My last successful deployment was in March and I have not done anything until today. I update just the SEO component with the meta tag, the title & the description. And that is an ERROR that I do not know how to solve.

I even went back to the previous successful deployment to deploy it but I saw the same error message. I also npm install --save-dev @babel/plugin-proposal-class-properties but nothing works.

It works on my local.

Please help me solve this issue.

Thank you.

Hey there, @robot :wave:

Thanks so much for reaching out. It looks like this thread has been a bit quiet this past week. Are you still encountering this error? If you are, can you share any additional debugging steps you have taken since posting? Thank you :slight_smile:

Thank you for the reply. I have been waiting for someone to help me since I still have this issue.

I can not provide you more debug steps because I have no ideas what is going on. All I know is it was working without any issues and I did not make any changes in the code except I updated the meta stages info.

I hope you can help me resolve this issue.

Thank you.

hi there robot, could you link or paste a full deplog log for us please?

hmm, interesting. Seems like maybe something is not right with your build cache.

does the error also occur when you try β€œclear cache and redeploy”? my hunch is that some dependency maybe got updated behind the scenes, and now the cache does not contain the information that is needed. Will you try the idea i just mentioned and let us know?

I did it. Same error!

Hi, @robot. Yes, that package isn’t present in you package.json. Have you tried adding it?

Hi! I’m not sure if this is the correct place to speak on this but I’m having a very similar issue to this.

I posted my problem in the above post. Just found this very post we’re on.

I also had a successful deployment back in very early May and decided to pick the project back up yesterday and have mysterious build problems. Rolling back everything to the last successful deployment also does not work for me. Even though the code should be exactly the same. I cleared the build cache and everything.

The first error is also a dependency error. It should be handled by package-lock.json but I manually installed all the missing dependencies that caused the builds to error anyways. After fixing those, it then threw various errors regarding typescript loaders. Also similar to @ robot’s problem it seems. At least regarding the loader.

Not sure what to do about my case either and I thought it would help to provide some information regarding this thread too. You suggested adding the package to package.json which I had done through my debug steps and that only lead to further issues. Everything works locally.

Hi, @NoahBres. While the issues are similar I don’t think they are similar enough to troubleshoot both in a single topic.

Both issues involve the use of npm and reference missing dependencies but that is the only similarity. The static site generators used and the dependency which are missing are completely different so I do think keeping the two topics split is best.

Most definitely! Apologies if I’m contributing to some noise here. Not expecting to troubleshoot both in this one topic for sure! Just thought it would be helpful to point it out if these errors did happen to be linked if it were a bug on your end! Because it does seem like something changed with the build image in May that affected us both (because of the previously successful builds no longer working).
