Nuxeo REST API - Blob.ConcatenatePDFs - 500 Internal Server Error [SOLVED]
Hi,
I want to merges blobs but when I try `nuxeoClient.operation('Blob.ConcatenatePDFs') .params({ filename: fileName }) .input(blobList) .execute()` , I get {“entity-type”:“exception”,“code”:“org.nuxeo.ecm.automation.InvalidChainException”,“status”:500,“message”:“Failed to invoke operation: Blob.ConcatenatePDFs”} ? And in nuxeo server side I have :
****** chain ******
Name: Blob.ConcatenatePDFs
Exception: InvalidChainException
Caught error: Cannot find any valid path in operation chain - no method found for operation 'Blob.ConcatenatePDFs' and for first input type 'java.util.ArrayList'

According with http://explorer.nuxeo.com/nuxeo/site/distribution/Nuxeo%20DM-8.3/viewOperation/Blob.ConcatenatePDFs, We don't need Document path to use this OP ? blobList is enough ?
Must I update my nuxeo platform to have Blob.ConcatenatePDFs Operation in REST API ?
Thanks for your helps
Hi Thomas,
Here is my CustomConcatenatePDFs from studio (cf : [Capture d’écran 2018-01-18 à 10.11.21.png])
nuxeoClient.operation('CustomConcatenatePDFs')
.params({
filename : fileName,
url : pdfUri })
.input(docs) //List of doc to have automatic loop
.execute()
but when I get ressult client side I always have blob ([Capture d’écran 2018-01-18 à 10.11.01 (2).png]) with no stream and name ? MergedPdf : { type : 'text/plain', size : 13284832} It supposed to be a pdf file ?
thanks
Hi Thomas,
I solved my issue by creating a customScript server side in studio though automation chains and it works fine.
Thanks a lot
Hi Thomas,
If I use Automation scripting to do my merge operation server side, It will works ? It will return readable file (blob) in client side ?
Thanks
You can't use Blob JSON definition from a JSON document properties as input of an operation, Nuxeo won't be able to decode it.
For your use case, I would create a custom chain CustomConcatenatePDFs such as:
- Document.GetBlob: {}
- Blob.ConcatenatePDFs: {}
And then call it through:
nuxeoClient.operation('CustomConcatenatePDFs')
.input(doc) // or just the document id/path if you don't event need to fetch the wole document
.params({ xpath: 'file:content', filename: fileName })
.execute()
This way, everything will be done server side: the first operation will retrieve the Blob at file:content from the given document as input and pass it to the Blob.ConcatenatePDFs operatrion as input.

So I create a custom chain to get my Blob, then a I do an iteration of it to have blob list and then call Blob.ConcatenatesPDFs OP to get Merged Blob PDF?
I go to try It.
Thanks
let file :Blob = doc.properties['file:content']; it will be only one blob, always.I Thomas,
I use latest version of JS client (3.4.1), nuxeo version 8.10 and my BlobList (blob) look like
let file :Blob = doc.properties['file:content'];
such as
blob : {data : "[https://server/nuxeo/nxfile/default/2c19d2f0-212e-4f84-9c56-f61c497e9ff9/file:content/CDE-2018-000021%20DEVIS%20MANUEL%20HAVAS.docx](https://server/nuxeo/nxfile/default/2c19d2f0-212e-4f84-9c56-f61c497e9ff9/file:content/CDE-2018-000021%20DEVIS%20MANUEL%20HAVAS.docx "https://server/nuxeo/nxfile/default/2c19d2f0-212e-4f84-9c56-f61c497e9ff9/file:content/CDE-2018-000021%20DEVIS%20MANUEL%20HAVAS.docx")"

I tried doc.getBlobs() but I have blob : { type : application/vnd.openxmlformats-officedocument.wordprocessingml.document, size : 13273}, that's all.
But I always have
