Help: Failed to execute query selector on element

Dash Python
1

hey guys, im trying t render a table on to a dash page,
the table renders perfectly but a few seconds later it crashes saying:
“Failed to execute ‘querySelector’ on ‘Element’: ‘td[data-dash-column=“AirSpeed 2900
40+40MHz
n48
Numerology=1,SCS=30Khz”][data-dash-row=“0”]:not(.phantom-cell)’ is not a valid selector”
anyone knows what this is and how come it successfully renders and only then disappears?

Hello @drgitt,

Welcome to the community!

It is really hard to say what is going on without a little bit more detail.

Could you please post an MRE?

Btw, I found that the solution was to not have qoutes " within the header of the datatable.
