Error while exporting the results

[varshasahasrabuddhe]

Hi I am using 'Robyn (dev) v3.12.1 and R-4.4.3 on GCP.

With higher Trials and iterations (14-9000), i get below errors

"Failed exporting results, but returned model results anyways:"
Error in grid.Call.graphics(C_lines, x$x, x$y, index, x$arrow): invalid hex digit in 'color' or 'lty'
stderr F

Thanks,
Varsha

Yes, I also have this problem. Judging from warnings(), the color palette is limited to 13 values ("This manual palette can handle a maximum of 13 values.")

I'm having the same issue where I cannot get a Robyn output because of this

Did you ever resolve this @varshasahasrabuddhe ?

I got it to run again as expected by going back to previous versions of RStudio and its packages.

This is my setup:

R version 4.3.3 (2024-02-29)
