Hi Alur

Could you please confirm whether the apex class or trigger already exist in your dev org? If you're on the developer console press Ctrl + O and search for contactPointsTrigger They might be already existing.

Sometimes it happens due to the network connectivity issues.

if you need any assistanse, Please let me know!!

Kindly mark my solution as the best answer if it helps you.

Thanks
Mukesh

HI Auler,
There could be multiple causes for this error. What operation are you performing - DML or deployment? If DML, this error is caused by unique field constraint on the object.

Came across this post https://salesforce.stackexchange.com/a/79800/80089 which has elaborate details on debugging this error. The post also has other users' experiences of what worked for them and that should help you.

If this information helps, please mark the answer as best. Thank you
