Element Android doesn't send a JSON body for POST /rooms/{roomId}/receipt/{receiptType}/{eventId}

[reivilibre]

Element Android currently doesn't send a JSON body for POST /rooms/{roomId}/receipt/{receiptType}/{eventId}.

It should send a request body, even if that would be the empty body {}.

This was noticed as part of recent changes in Synapse v1.40.0rc1; a workaround (matrix-org/synapse#10531) will be put into Synapse v1.40.0rc2:

The spec is, at the time of writing, wrong (see matrix-org/matrix-spec-proposals#3237) but is being fixed by matrix-org/matrix-spec-proposals#3238.

Fixed in EA 1.2.1
