While verifying integrated security using for all REST API's, I used gfsh to start a locator, a server, and create a single region with 2 data entries. I then wrote and deployed a simple function (io.build.test.Sample).
In a separate terminal I was able to successfully get a list of the function using the GET API, but when I tried to execute the function using the following command:
curl -u dataWriter:123 -X POST -i http:80/gemfire-api/v1/functions/io.build.test.Sample
I get the following exception:
"org.apache.geode.cache.execute.FunctionException: Function named io.build.test is not registered to FunctionService"
Note: the name of the function, Sample, was dropped in the exception message.
When I implemented the getId() method for the function to shorten the name to 'foo', the same POST API worked successfully:
curl -u dataWriter:123 -X POST -i http:80/gemfire-api/v1/functions/foo
Is there a limit to the length or format for the function name with the POST API?
