Excel export error

[giuetr]

Hi,
I get the following error when running the script:

100%|███████████████████████████████████████████| 1/1 [00:04<00:00, 4.63s/it] Traceback (most recent call last): File "insider_1.py", line 134, in <module> insider_trading_all(symbols, date, export_file, file_name) File "insider_1.py", line 115, in insider_trading_all combo = pd.concat(dfs) File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pandas/util/_decorators.py", line 311, in wrapper return func(*args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pandas/core/reshape/concat.py", line 304, in concat sort=sort, File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pandas/core/reshape/concat.py", line 351, in __init__ raise ValueError("No objects to concatenate") ValueError: No objects to concatenate

It seems that the companies and data are correctly scraped but the concatenation of the resulting dataframes doesn't work.

The problem arises both when fetching tickers from a csv and when using a single ticker.

Thank you for your time
