list index out of range when comparing more than 2 dataframes

[alikleit]

Current Behaviour

The following example is from the docs (modified a bit for testing against my files):

from ydata_profiling import ProfileReport, compare

train_df = pd.read_excel("datasets/Train.xlsx")
train_report = ProfileReport(train_df, title="Train")

test_df = pd.read_excel("datasets/Test.xlsx")
test_report = ProfileReport(test_df, title="Test")

validation_df = pd.read_excel("datasets/Test.xlsx")
validation_report = ProfileReport(validation_df, title="Valid")


comparison_report = compare([train_report, validation_report, test_report])

# Obtain merged statistics
statistics = comparison_report.get_description()

# Save report to file
comparison_report.to_notebook_iframe()
# comparison_report.to_file("reports/comparison.html")

Expected Behaviour

To Generate a comparison report

Data Description

Files:
Test.xlsx
Train.xlsx

Code that reproduces the bug

Tried Both:

comparison_report.to_notebook_iframe()
# comparison_report.to_file("reports/comparison.html")


Throws:
