Can confirm I have the same issue but just haven't had the time to look into and report

Most Windows 10 client may not have included HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/csv on registry.
And if Excel was installed on it, the value of HKEY_CLASSES_ROOT\.csv\Content Type may have been registered as application/vnd.ms-excel .
Will the file type you upload change if you change these registry entries?

[noyome123]

HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/csv did not exist
HKEY_CLASSES_ROOT\.csv\Content Type is application/vnd.ms-excel

add text/csv,
and change ContentType to text/csv
but Changing the settings didn't fix it

As a test 1....

1. add /var/www/aaaa.csv
2. go to https://hogehoge/aaaa.csv
3. aaa.csv has been downloaded

As a test 2 ....

1. upload aaaa.csv to RocketChat
2. download from RocketChat
3. aaa.csv.xls has been downloaded

Same with version 3.15.0. I wonder that no one really cares about this issue?

Same issue here. Seems only affects csv files.

[Feijai]

app>api>server>lib>getUploadFormData.js
using node_module "Busboy" which not support csv file.

maybe that is the point
