onCreateNode: Placeholder from Static instead of createRemoteFileNode

[el-j]

in some cases the remoteFile may not be there and cannot be created. this will lead to a problem with later plugins in the structure. now i try to integrate a simple fallback to an local image in my static folder.

sadly i am failing to source the image node ... this is what i normally do without any trouble:

let fileNode = await createRemoteFileNode({
            name: `${node.frontmatter.title}`,
            publicURL: fullHdPoster,
            url: fullHdPoster,
            parentNodeId: node.id, // id of the parent node of the fileNode you are going to create
            createNode, // helper function in gatsby-node to generate the node
            createNodeId, // helper function in gatsby-node to generate the node id
            cache, // Gatsby's cache
            store, // Gatsby's Redux store
          })
          console.log(fileNode);
          if (fileNode) {
            node.frontmatter.videoPoster___NODE = fileNode.id
          }

but how i include a file from static folder if (for any reasons) the createRemoteFileNode is not possible/not wanted?
i tried to integrate the placeholder image like that without luck.

const imgPath  ='./static/img-placeholder.jpg'
const { name, ext } = path.parse(imgPath) // get file name & extension
const absolutePath = path.resolve(__dirname, imgPath)
const data = {
             name,
             ext,
             absolutePath,                  
             extension: ext.substring(1),
          }
const imageNode = {
            ...data,
            createNode, // helper function in gatsby-node to generate the node
            id: createNodeId(`${node.frontmatter.title}_placeholder`),
            parentNodeId: node.id,
            children: [],
            internal: {
              type: 'PlaceholderFile',
              mediaType: 'image/jpeg',
              contentDigest: createContentDigest(data),
            }
          }
          createNode(imageNode)
          node.frontmatter.videoPoster___NODE = imageNode.id

sadly it fails with the next plugin, wants to have an image ...

Is there something like createFileNode? for a file from Staticfolder e.g.?

Edit: it fails in build because missing the
childImageSharp of this placeholder image.
