Hi all,

We have been using the Send Messages API with template buttons at https://graph.facebook.com/v18.0/me/messages.

I received an error with the following details: Code: 100, SubCode: 2018023, fbtraceId: AlJOcqaDk5993l2-k7v0o8o, msg: (#100) Save attachment failure.

The error occurred only for PSID 4822705404446239; the others were successful without errors.

session_id: https://developers.facebook.com/tools/explorer/1621755161178887/?session_id=944758980529968

Any idea or any reported bug as I didn't find any?
