I'm learning DASH by building an app which grabs data from Finnhub.io via API and plots it.
I'm currently getting this problem when I change the input for the dash callback. It happens intermittently, and after a couple of refreshes it appears to work fine. However I would prefer if it would work off the bat 100%.
I've tried diagnosing the problem, and the error seems to appear at line 99 of:
fig = px.line(df1, x = df1.index , y ="c") - data is indexed in date time and "c" is the column name of the closing price of the stock as fetched.
I was wondering if anyone was having a same/similar issue or could assist.
Thank you very very much in advance!
