NULL Result from coloc.susie

[htqqdd]

I encountered an issue when using the package, specifically with the coloc.susie function. After preparing my datasets and running runsusie on each, I attempted to perform colocalization analysis using coloc.susie. However, instead of getting the expected summary results, the function returned NULL.
Here is my code:
dataset1 <- runsusie(dataset1)
dataset2 <- runsusie(dataset2)
susie.res <- coloc.susie(dataset1, dataset2)
print(susie.res$summary)

Here is the screenshot of the two datasets after runing runsusie.

I'm not quite sure this is the correct output or a bug dealing with special data？
Thank you for making such a useful package.
