How did you define your table? It sounds like you did not specify

post

as a primary key for this table.

``` const postsTable = new cloud.Table( 'feedPosts', 'postId' ); // Create an API endpoint const endpoint = new cloud.API( 'feed-posts' ); // Add a new Feed Post endpoint.post( '/posts/add', ( req, res ) => { const feedPost = JSON.parse( req.body ); console.log( feedPost ); postsTable.insert( { postId: feedPost.postId, title: feedPost.title, body: feedPost.body, } ).then( () => { res.status( 200 ).json( feedPost ); }, res.status( 500 ).end() ); } ); // Get a single Feed Post endpoint.get( '/posts/{postId}', ( req, res ) => { const post = req.params.postId; console.log( post ); postsTable.get( { post } ).then( ( value ) => { res.status( 200 ).json( value ); } ); } );

That's right - that JS code is a shorthand for

postsTable.get( { post: post } )

, so it's getting the primary key

"post"

whose value matches the value of

post

.
