SharePoint manifest load error SPFx and React

Question

We are trying to make an PWA which works offline. Until December last year it was working fine, we could load the app, go through the content, change pages.

Something happened and we are not able to load the app anymore and we have this error. We have tried a lot of things on the service worker and nothing has worked.

If someone knows how to solve this, please let us know.

Thanks

Hi @Tael Oliveira

This error probably means that you are somehow using react version 16.8.5 that may not be compatible with SPFx version you are using. See the compatibility matrix here. You will need to check if the react version support your environment by the link.

The app you are referring to might be created servral years ago. So you could just use the tooling from that time, i.e. node 10.x. There is a great node version manager aka NVM tool that allows you to use multiple independent node versions. You could try node version like following

> node --version
v10.x
> npm ci
> npm i -g gulp-cli
> gulp serve
