Issue with "sharing violation" on temp folder

DanDanDanDanDan

Hello there,

I am using ApplicationXtender 16's REST API to export jobs. I am having an issue when I make concurrent requests to the same endpoint/file. I get the following error:

{"ErrorCode":9999,"Message":"Save page files: Encountered a sharing violation while accessing C:\\Users\\AX758D~1.IMP\\AppData\\Local\\Temp\\docx_560130.docx. Job failed! Unknown error","InnerException":null}

This is my post request to export the file:

let req = {
      method: 'post',
      url: `/AXDocExportJobs/${appId}`,
      headers: {
        'Accept': 'application/vnd.emc.ax+json',
        'Content-Type': 'application/vnd.emc.ax+json; charset=utf-8',
      },
      data: {
        "ExportColdFormOverlay": 1,
        "IsExportCold": false,
        "HideAnnotation": false,
        "Documents": [{
          "AppID": appId,
          "DocID": docId
        }],
        "pageRange": pageRange,
        "pageNum": 0,
        "pageVersionNum": 0,
        "subPageRange": null,
        "UsePDFFormat": isPDF,
        "ExportIndex": false,
        "ExportImage": false,
        "IsOpenDocument": true,
        "queryContextId": null,
        "idxes": null
      }
    };

Once the job has started, I use the following to check on the status:

return {
      headers: {
        'Accept': 'application/vnd.emc.ax+json',
      },
      method: 'get',
      responseType: 'arraybuffer',
      url: `/AXDocExportResults/${jobToken}`,
    };

The code above works most of the time, but it fails when multiple requests are made at the same time for the same file (docId).

I believe Windows throws this error when you try to access a file that's already in use. What am I missing here? Is there a way to check out this file before exporting it, or perhaps check if a file is already being exported before initiating a new export job?

Any help that points me in the right direction is much appreciated. Thanks.
