CREATE REL TABLE with MAP causes "Error: Copy exception: Invalid type for property list creation." + CLI freeze

[sapalli2989]

Works:

CREATE NODE TABLE T(name STRING, PRIMARY KEY(name));
CREATE NODE TABLE T2(name STRING, myprops MAP(STRING,STRING), PRIMARY KEY(name));
CREATE REL TABLE KIND_OF(FROM T TO T);
CREATE REL TABLE KIND_OF2(FROM T TO T, mystring STRING);

Causes error:

kuzu> CREATE REL TABLE KIND_OF3(FROM T TO T, myprops MAP(STRING,STRING));
Error: Copy exception: Invalid type for property list creation.

Now subsequent commands afterwards cause CLI freeze/loop:

kuzu> MATCH(n) return n;
// CLI freezes / idles

(Version: kuzu compiled from today's sources)

Hi @sapalli2989 , thanks for your issue! There are currently some data type support missing in rel table, including UNION, MAP and STRUCT. Will add them soon after a rework of the storage for rel table 😄 , though we should throw errors during the binding stage. And the CI freeze looks like a bug.

Hi @ray6080, good to know. Just being curious: Is there a rough ETA for storage rel table rework? Until then, I'd suggest to change error message to something like "Error: MAP, UNION, STRUCT currently are not supported in REL TABLE".

The rework will be done within this month.
For the error message, we do plan to change it in our coming bug fix release so it's more clear.
