How to exclude a locale in V4?

In the old plugin "gatsby-source-prismic-graphql", there was an option of langs, which was an array of strings where you could define the locales you wanted to fetch.

Now, on "gatsby-source-prismic", there is no such option, but there is a lang option, which according to the docs: "Set a default language when fetching documents. The default value is '*', which will fetch all languages."
And takes a string as value.

So the question is, how can I exclude a locale that exists in Prismic, but I don't want in my gatsby site (just yet)?

Hello Juan Manuel, thanks for reaching out and for bringing this to our attention.

I'm not entirely sure if this is possible at the moment. I will communicate this concern with the team in charge of maintaining the plugin and inform you about any news.

Hello again Juan Manuel hope you're doing great!

So, there won't be a similar option for the new plugin but the workaround is as follows: For excluding a lang you can use the filter option when writing a GraphQL query

It would look something like this:

query MyQuery {
  allPrismicPage(filter: {lang: {nin: ["fr-fr"]}}) {
    nodes {

Where nin is a list of languages to exclude (nin = “not in”)

Let me know if this is helpful for you.
