Uncaught Error: Assertion failed: Expecting an unsigned number (SOLVED)

I hit this problem and, while I can see other people have asked about it, I couldn’t see any solution. I resolved the error, but I thought that I’d post something here (not least in case I hit it again and cannot remember the answer! :slightly_smiling_face: )

I was getting an error on a setDataAtRowProp. The cause of the problem was that I was trying to write a value into a column that did not exist. In my case, for setDataAtRowProp(row, prop, value), I had a typo in the prop name. I fixed the typo and, no surprise, the problem went away.

Hi @woody

Thank you for your input, I’m glad you found the solution. I will close this topic and keep it as probable solution for others.
