How to generate preview of content load onto a workflow via ReST API

Hi there,

I'm using the APS 1.11.0 REST API to add content to a process instance as follows:

http://localhost:9090/activiti-app/api/enterprise/process-instances/768072/raw-content

In the call I post a file that gets uploaded and I can see content attached to the process using:

http://localhost:9090/activiti-app/api/enterprise/process-instances/768072/content

{

"id": 261284,

"name": "MyTW_Bill_900011423716_26_07_2021-2.pdf",

"created": "2021-08-06T09:50:34.655+0000",

"createdBy": {

"id": 1,

"firstName": "Mr",

"lastName": "Administrator",

"email": "admin@app.activiti.com",

"pictureId": 2002

"relatedContent": false,

"contentAvailable": true,

"link": false,

"mimeType": "application/pdf",

"simpleType": "pdf",

"previewStatus": "queued",

"thumbnailStatus": "queued"

}

You can see at the bottom of the JSON that the previewStatus and thumbnailStatus are "queued".

What do I have to do to force APS to process this, change the status to "created" and therefore allow me to retrieve the preview rendition?

I have a custom Angualr app that is making the REST calls, but if I run the same call via Postman, APS still refuses to generate the preview. If I upload the same file via Activiti App then the preview is generated.

Thanks

Paul
