Error deploying to Netlify:

I sourced my Gatsby site with Prismic.io and locally everything works well. The problem is when I am trying to deploy it to Netlify I get the following error:

I hope you can help me! Thanks

@leonstern10 i’ve picked up on you issue and it seems that your issue lies with the layout component. Inside it you have multiple StaticQuery and that’s a Gatsby limitation. You can only have one StaticQuery per component/file. This link refers to the hook approach of the static query, but the same applies for StaticQuery component. The good news is that you already have the query in place so no changes there, so you would only need to remove the second StaticQuery component for the Footer and you should be good to go.

A quick tip for you, before deploying to Netlify or any other host, issue a gatsby build && gatsby serve to generate a local production build and emulate a production server so that you can see if everything is in working order with your site so that you don’t run into some issues.

Feel free to provide feedback so that we can close this issue, or continue to work on it until we find a suitable solution.

@leonstern10 no need to thank. Glad that i was able to help you solve your issue. Going to close it as per your instructions
