Hello, I have the same problem, have you perhaps found a solution yet?
gatsby-source-strapi" threw an error while running the sourceNodes lifecycle:
The plugin "gatsby-source-strapi" created a node of a type owned by another plugin.
The node type "File" is owned by "gatsby-source-filesystem".
Error: The plugin "gatsby-source-strapi" created a node of a type owned by another plugin.
The node type "File" is owned by "gatsby-source-filesystem".
If you copy and pasted code from elsewhere, you'll need to pick a new type name
for your new node(s).
