Try to add new observer server using reconfig API, server gets added as participant.
STEPS:
# create 3 node cluster.
{code}
server.0=127.0.0.1:11223:11224:participant;127.0.0.1:11222
server.1=127.0.0.1:11226:11227:participant;127.0.0.1:11225
server.2=127.0.0.1:11229:11230:participant;127.0.0.1:11228
{code}
# Suppose the 2 is the leader in the above cluster. Configure the new server as
{code}
server.2=127.0.0.1:11229:11230:participant;127.0.0.1:11228
server.3=127.0.0.1:11232:11233:observer;127.0.0.1:11231
{code}
# Connect to 1 and execute the reconfig command

{code}
# Verify sever 3. It was supposed to run as observer but it is running as participant
