subgraph not rendering with change to sample

[mycall]

I am having problems rendering this graph. Am I doing something wrong?

graph TB        
    subgraph old sys 2
        a2(new client)-->b2
        oc2(Old client)-->b2
        a3(test)-->b2
    end

    subgraph old sys 1
        a1(new client)-->b1(sys1 server)
        oc1(Old client)-->b2(test)
    end

[mycall]

error "Uncaught TypeError: Cannot set property 'label' of undefined" @ mermaid.js:10789

if (!_.has(node, "label") && !g.children(v).length) { node.label = v; }

Are there limitations to subgraphs?

Your graph works in the editor:

What version are you running on?

Check with the graph definition:

Perhaps it is how I am using mermaid.js. I zipped up my sample here: https://www.zipshare.com/download/eyJhcmNoaXZlSWQiOiI0ODUyZGU2ZC0zNTM1LTRlOWEtOTRhYy01YTczNjQyNTcxZjUiLCJlbWFpbCI6Im1wYWluZUBhY3RyYW5zaXQub3JnIn0=

any chance you can review the uploaded zip?

I did and found tab characters to be the problem. Replace with space and
it will work. Mermaid should handle the tabs eventually though.

Thank you, that solves my problem. I've been using tabs successfully without the subgraph feature but once I added subgraph, I was getting those errors.

Might be an easy regex to fix.
