Having trouble with the media upload process... somewhere.

[karsteny]

Hi! I'm quite new to using this (and also still pretty inexperienced in Java programming itself), so maybe it's just a simple mistake. The issue is that I cannot get any media (or at least the images I tried) to upload. I'm not too sure if its an issue with how I am reading the file to the Byte array, or syntax, but it always results in either javax.net.ssl.SSLException: Received fatal alert: record_overflow or java.io.IOException: Error writing to server, depending on the image.
Here is the code:

File file = new File("cover.jpg");
byte[] fileContent = Files.readAllBytes(file.toPath());
UploadMediaResponse media = client.uploadMedia("cover.jpg", fileContent, MediaCategory.TWEET_IMAGE);

The files are all <5MB and they appear to be read in correctly if I list out the contents of the byte array. The client instance itself will work just fine with other methods, such as posting a tweet.

Edit: Resolved in this post.

Can you check this example and try it on your side ?

Actually, it works also with your image :

Can you tell me if other post endpoints work fine ? Like are you able to post a tweet without images ?

testPostReplyTweetAndDeleteTweet is also failing on my side, I'm going to check it.

Edit : finally it works, it was just an account permission issue, I just authorised the read & write and now it's ok, you can see the result below :

Alright, I have actually resolved the issue myself.
I googled the error javax.net.ssl.SSLException: Received fatal alert: record_overflow to see what exactly could be and found someone on StackOverflow asking about a similar error but with the same details, and someone replied saying it was a bug with Java 11 and Java 12, and that it was fixed in 11.0.5 or 13. So I downloaded a 11.15 JDK and ran the program with that, and lo and behold, it posted just fine. What a strange bug. I guess this question is resolved now, thanks for all the help trying to debug it even though it was something that was wrong with Java itself.
