When Embedding tweet sometimes get Unexpected exception

Questions

Every few weeks, when I try to embed a tweet in an RTE using the built-in Embed function, it fails, no matter which tweet I choose, with an “Unexpected exception happened while trying to get oembed markup” error. I am using the TinyMCE package on my v16 install, so I don’t know if this is a core issue, a package issue, or a Twitter issue, and how to deal with it. Does anyone have any ideas? Here is the error stack

System.Text.Json.JsonException: 'e' is an invalid start of a value. Path: $ | LineNumber: 0 | BytePositionInLine: 0.

 ---> System.Text.Json.JsonReaderException: 'e' is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.

Does anyone have any ideas on this? When it breaks it litterly stops work for the day. It will fix it’s self by the next day but losing a day of work because of the problem is costly

Hi Matthew, sorry I didn’t see this. Would it be possible to post an issue on the package issue tracker here?

I can take a look and see if I can reproduce it or figure out what is going on here

Thanks,
Jason

Hi Jason,

I ended up opening a bug report on the CMS github page and they found it was a bug in the twitter embed provider which they have fixed so I am all set but thank you.
