Saving pdf attachment from base64 content but getting mime type text/plain

Hello,

I’m trying to save a pdf attachment directly from backend.
I use the string base64 content which I convert into an array of bytes then an input stream.

Here’s my snippet of code:

dVinciAtt -> {
    ByteArrayInputStream inputStream = new 
    ByteArrayInputStream(dVinciAtt.getContentAsBase64().getBytes());
    // We use saveAttachment from deveeDocumentService instead of AttachmentService to isolate the transaction and be able to use the data created just after this transaction
    AttachmentHeader attachmentHeader = deveeDocumentService.saveAttachment(inputStream, ...);
}

@Transactional(propagation = Propagation.REQUIRES_NEW)
@Override
public AttachmentHeader saveAttachment(InputStream is, String filename, String documentModelName, String pathToField, List<AttachmentAnnotation> annotations) {
	return attachmentService.saveAttachment(is, filename, documentModelName, pathToField, annotations);
}

The base64 content is:

"contentAsBase64": "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

It begins with “JVBERio” which is indeed the application/pdf mime type magic number so I don’t understand why it creates an attachment with the type 'text/plain".

Thanks for you reply

hello,
With string base64 content, you need decode it.

String base64Str = "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";

It works for me.

Thank you, I didn’t think about the way I decoded it, so sorry!
