[N1QL] javascript functions are not being added to the /api/v1/functions endpoints everytime

add this javascript function:
[root@localhost logs]# curl -X POST http://localhost:43381/api/v1/functions -H 'content-type: application/json' -d '{"name":"math","code":"function add(a, b)

{ let data = a + b return data }"}'

add this javascript function
[root@localhost ~]# curl -X POST http://localhost:43381/api/v1/functions -H 'content-type: application/json' -d '{"name":"math","code":"function mult(a, b) { let data = a * b; return data; }"}'

curl the endpoint to see if they are there:
[root@localhost ~]# curl http://localhost:43381/api/v1/functions -H 'content-type: application/json'
{"name":"math","id":"85:70:cc:46:27:c9:e5:d","code":"function add(a, b) { let data = a + b return data }

"}

Second javascript function was never added. This seems to be an intermittent error, both Evgeny and I have seen it.

If i try to create a function based on the second method and use it i get an error:
CREATE FUNCTION javaScriptmult() LANGUAGE JAVASCRIPT AS

{ "math", "mult" }

select javaScriptmult(6,1)

this query hangs or throws an error (i've seen both behaviors)

When i try to cancel it i see this in the logs:
