JavaScript filesGetThumbnailBatch() returns success, no thumbnails. Anyone have example code?
I am using NodeJS and trying to get batches of thumbnails in groups of (up to) 25 using the API function filesGetThumbnailBatch(arg)
I am getting a successful result and an array of responses, but the "thumbnail" value is an empty string.
If I make a call for a single thumbnail using
filesGetThumbnail(arg)
I get back a result which has a key of "fileBinary" included which contains a buffer with the image data.
fileBinary: <Buffer ff d8...
I know that the endpoints are different, a single image is a "content-download" endpoint and the batch endpoint is an "RPC", but the RPC docs state that results are returned in JSON. What am I doing wrong to batch get the thumbnails? Anyone able to share some sample code? More info below:
Sample code:
// get thumbnails for the current batch of files var thumbs = await dbx.filesGetThumbnailBatch({ entries: files.entries.map(function(entry){ return { path: entry.id, format : {'.tag': 'jpeg'}, size: { '.tag': 'w2048h1536'}, mode: { '.tag': 'strict' } } }) });
Sample Output of successful call to
filesGetThumbnailBatch(arg)
but lacking thumbnails in results:
{ entries: ocv2-server | [ { '.tag': 'success', metadata: [Object], thumbnail: '' }, ocv2-server | { '.tag': 'success', metadata: [Object], thumbnail: '' }, ocv2-server | { '.tag': 'success', metadata: [Object], thumbnail: '' }, ocv2-server | { '.tag': 'success', metadata: [Object], thumbnail: '' }, ocv2-server | { '.tag': 'success', metadata: [Object], thumbnail: '' }, ocv2-server | { '.tag': 'success', metadata: [Object], thumbnail: '' }, ocv2-server | { '.tag': 'success', metadata: [Object], thumbnail: '' } ] }
console output of a single item within the results of
{ '.tag': 'success', ocv2-server | metadata: ocv2-server | { name: '03_march_2017-2166.jpg', ocv2-server | path_lower: '/<path-here>/03_march_2017-2166.jpg', ocv2-server | path_display: '/<path-here>/03_march_2017-2166.jpg', ocv2-server | parent_shared_folder_id: '1405518608', ocv2-server | id: 'id:ivylSwty9kAAAAAAAAABng', ocv2-server | client_modified: '2017-03-16T03:35:12Z', ocv2-server | server_modified: '2017-03-16T03:37:11Z', ocv2-server | rev: 'af53c809b0', ocv2-server | size: 10792733, ocv2-server | media_info: [Object], ocv2-server | sharing_info: [Object], ocv2-server | content_hash: 'e8320ea5b7295fed9ebaecf4b61789322b0e2ab3f17922675979d5bd6ab5f778' }, ocv2-server | thumbnail: '' }

Thanks for the report! You don't appear to be doing anything wrong. The 'thumbnail' can be empty, e.g., if the corresponding file is empty. That doesn't seem to be the case here though, so we'll need to look into it.
I just tried this myself though, and it worked for me. (I.e., 'thumbnail' was not empty.) Would you be able to supply a sample file that this issue reproduces with? (E.g., the '03_march_2017-2166.jpg' file, or whatever you're comfortable sharing.) You can also open an API ticket if you'd prefer to share privately. Thanks in advance!

Hi Greg, thanks for the support!
Here are the images I was using as a sample set for the batch request:
https://www.dropbox.com/sh/qxr4id51pn1s7yf/AAC92AF8NyaluTrmimRgKNQna?dl=0
They are all about 12MB each, so not over the 25MB limit. I am able to get them if I request them individually.
Let me know if I should also open a ticket.
