4010: Pinned line outside environment.

HTTP status: 422.

The number this conversation already uses is one of yours, but it is not in the environment this key acts in, and a key only ever sends from numbers in its own environment. Nothing was sent, no chat was forked and the pin was not moved. A conversation never moves to another number. The refusal names that number even though this key cannot otherwise list it, because it is your own number in another of your environments.

• Read error.context.pinned_from (the conversation’s current number) and error.context.available_from (a number in this environment that could serve, when one exists).
• Send with a key that acts in the number’s environment to continue the same conversation, or open a separate conversation from this environment by sending an approved template with from set to available_from.
