sourcebit-nextjs-cache.json Not Found

[slavakurilyak]

I am running Stackbit v0.3.44, using Next.js as a web framework and Contentful as a CMS.

When I try to deploy, Netlify log shows me:

Two issues come up during the deployment:

1. Cannot read property 'fields' of null.
2. cache file '/opt/build/repo/.sourcebit-nextjs-cache.json' not found

Thoughts?

Hi @slavakurilyak

It seems like sourcebit-source-contentful plugin gets an error while fetching data (Cannot read property 'fields' of null). So sourcebit-target-next couldn't save that data in a file and use it.

Which version of sourcebit-source-contentful plugin you are using?
I remember we fixed a similar problem and released a new version 0.6.4

[slavakurilyak]

@smnh Thanks for your reply!

I was using 0.6.2 which generated at 2021-01-29T06:24:38.534Z by Stackbit 0.3.44.

Consider bumping the Stackbit generator to include this fix and bumping Next.js to v10+ 😉

[rudietuesdays]

Hi, I'm having a similar issue as well. Using the following versions:

"next": "^12.1.0",
"sourcebit-source-sanity": "^0.4.5",
"sourcebit-target-next": "^0.8.3",

The file .sourcebit-nextjs-cache.json itself is built, but it's totally blank.

Would love any thoughts and guidance you have!

[smnh]

@rudietuesdays this can be caused by sourcebit-source-sanity misconfiguration, please check that the options for sanity projectid, dataset and token are all correct.

You can also add an empty plugin with console.log statement between sourcebit-source-sanity and sourcebit-target-next to validate that sourcebit-source-sanity actually returns some data.

If there is some data then sourcebit-target-next should store it inside the .sourcebit-nextjs-cache.json file when it runs.

module.exports = {
    plugins: [
        {
            module: require('sourcebit-source-sanity'),
            options: { /* sourcebit-source-sanity options here */ }
        },

        ({ data }) => {
            console.log(JSON.stringify(data, null, 4));
            return data;
        },

        {
            module: require('sourcebit-target-next'),
            options: { /* sourcebit-target-next options here */ }
        }
    ]
};
