Unable to connect a node to Erlang debugger ErlyBerly

Question

I am learning the Erlang debugger ErlyBerly. Started ErlyBerly as follows.

java -jar target/*runnable.jar

I have written a simple Erlang application with an infinite loop so that it keeps running. I started the node from erl CLI. Please note that both the Erlang node and ErlyBerly are running on the same Linux machine. The node is listed in ErlyBerly. When I tried to connect to the node, I am getting an error "cannot connect to peer node". What could be the reason?

$erl -sname node
(node1@vm-alarm)1>maths:f().
.....

I have tried with a long node name [email protected] as well. The same error is seen.

The Erlyberly readme page says that "Just make sure that the runtime_tools application is available in the code path. If the node was run using erl directly then it will be available by default". I did not understand this fully. What is runtime_tools? How to run the node using erl directly? Please help me in understanding this.

Following error message is shown:

Answer 1

Mostly it is because of the error "rejected since it cannot handle ["BIG_CREATION"]" while connecting to the node.

To fix it:

You must edit jinterface package part in pom.xml and make it download from com.github.rafaelmsoares instead of com.github.andytill

eg:

<dependencies>
    <dependency>
        <groupId>com.github.rafaelmsoares</groupId>
        <artifactId>jinterface</artifactId>
        <version>1.11</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
