Syntax error even with correct syntax

[chripu]

Describe the bug
Rendering a complex graph (flowchart) results in a "syntax error" even if the syntax seems correct.

To Reproduce
Try rendering this file.
test-graph-working.txt

Now add the following link:
item-2491 -.->|RelationA| item-2501;

Try rendering the file (added the link above in line 2):
test-graph-failing.txt

Expected behavior
A rendered graph.
Or a different error message if the graph is too complex to layout!?

I miss the program informing the syntax error and showing the line with it instead of just "syntax error" when opening the output file. Although I might be an ignorant of the program features as I just learned it.

Having the same issue with Mermaid Confluence plugin. All I'm getting is "syntax error" without any information about what goes wrong. All I can do is tentatively remove lines from the file and copy/paste them somewhere, as I cannot find any syntax for comments. Without a declarative tool such as Mermaid, all I have to make diagrams are point and click tools such as draw.io and it becomes very tedious for me to make diagrams.

Any updates here? I'm experiencing a similar issue. Some kind of information on the syntax error would be immensely helpful.

@chripu I am not able to render the chart from test-graph-working.txt in Notion. I get the error:

Unknown error: TypeError: Cannot set properties of undefined (setting 'order')

Mermaid Chart will be reviewing this tomorrow as a possible candidate to include in a list of fixes we will be working on for the open source project
