Dynamic spec returns 0 payload/value #12

Open Eze-DP opened 2 years ago

Eze-DP commented 2 years ago

When using dynamic specs, it only seems to work when the option type is set to string. All other types return 0, which is incorrect. This behavior can be seen in the buffer-parser examples provided by the package.

I suggest to create a buffer node with same spec and debug whole msg (there's a msg.specification where you can check spec defined on that node) usually you are missing, offset, or any other non obvious parameter for that kind of parsing

I have noticed this same behaviour and managed to get a working output when using 'mask': '' under the items properties.

It works using 'mask': '' under the items properties. Thanks @woytekbode
