Cite Dataset - BibTeX - Firefox json error

[ahmahdy]

I encountered an error while clicking on BibTex under Cite Dataset through Firefox as below, It works fine on chrome or safari.

Error
Page: Dataset page "dataset.xhtml"
Action: Clicking button "Cite Dataset--->BibTeX"
Browser: Firefox 60.8.0esr (64-bit)
Dataverse: 4.10.1
Occurrence "Audience": Everyone
Error Message: "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data"

I was able to replicate this in demo (v. 4.15.1), but should also note, that when clicking the "Raw Data" tab in the Firefox browser (see screenshot above), you get the same results you see in Chrome and Safari (see below).

Maybe there is a clue in the response headers:

Thanks @ahmahdy and @mheppler, we'll get a fix for this in the next sprint for inclusion in a future release.

Content-Type: application/json

This is why. Dataverse is asserting that BibTex is JSON. I assume this should be text/plain or something. Not sure.

I'm going to guess that response.setContentType("application/json"); here is the line that controls it:

https://github.com/IQSS/dataverse/blob/v4.15.1/src/main/java/edu/harvard/iq/dataverse/FileDownloadServiceBean.java#L434

Heh, it looks like I added FIXME above it. 😄 I thought this bug looked familiar!

[ahmahdy]

while searching I found that other people fixed this by saving the file with ANSI encoding instead of UTF8. I hope this helps.

Added response.setCharacterEncoding("windows-1252"); (ref) to FileDownloadServiceBean.java, but still seeing the syntax error in Firefox. Leaving for the actual Java developers.
