Unable to download in DMS using CAPM NodeJS

[cdan]

I am able to upload file and download file from postman successfully in DMS .Also completed the upload part from external file and I am able to download it from postman. I am getting the buffer but while performing from NodeJS get call for download using ?objectId='<value>' for downloading from my attachment(also passed responseType:buffer in get call). Also passed content-type: '<file-mime-type>',content-disposition. Still facing some issue when I use external service for downloading. For example, if I upload a png file I am not able to see the image. Any help would be appreciated.

My issue is with the file when it downloads. When I upload from my CAPM Node JS, I am able to preview it from DMS API. But when I call the DMS API from my Node.js I am unable to dowload the array buffer returned in my service. Its previewing image in the following format

Could you check source code of https://github.com/vneecious/sap-cap-sdm-plugin that I am using in my app. Or just use sap-cap-sdm-plugin like me.

Thank you so much for helping. I found the solution it was CAP interpreting any retrieved file as UTF-8 while this is not always matching the codeset of our file. So we have to use SAP Cloud SDK to bypass this UTF-8 conversion as it allows us to specify the Response Type to be the raw buffer which was also present within the plugin you used
