I am using this schema to file upload:

mutation{
     uploadImg (file: Upload!): File @resolver(class: "\\Test\\Cgraphql\\Model\\Resolver\\UpImg") @doc(description:"Upload img")
}

But getting error:

Type \"Upload\" not found in document.\n\nException #0 (GraphQL\Error\Error): Type \"Upload\" not found in document.\n#1 GraphQL\Utils\ASTDefinitionBuilder->internalBuildType('Upload',

Please let me know how can we upload image in graphql.

  • just pass the String instead of upload and do your upload script in you resolver.

You see this error because you should describe new input type which called "Upload". Your schema says: There is mutation called "uploadImg". It has one required parameter called "file". Input type of data for "file" should be "Upload" (not "String", not "Int", but "Upload"). And this mutation returns data with type "File". So, Magento can't find any declaration for input "Upload". For example, see "createCustomer" mutation and input "CustomerInput"
