Configuration problems

[iancg1]

Good day! First of all, I'd like to thank the ECDC team that made this R package. It is very promising and I really look forward to using it to improve epidemic surveillance in our country. However, I'm currently stuck configuring epitweetr. I'm at the configuration page, but clicking the "activate" button on Tweet search doesn't make the system run. I have followed all the directions on the vignette and downloaded all the necessary dependencies, as well as setup the home environment for Java. I'm seeing the following on the RStudio console:

library(epitweetr)
Warning message:
package ‘epitweetr’ was built under R version 4.1.1
epitweetr_app('C:/Users/user/Documents/epitweetr_data')

Where did I go wrong? I'm new to R as well (we mainly use Stata here) so please bear with me. Thank you.

Best,
Ian

Update, I got it somewhat running now by installing a 64-bit Java (The Java website defaults to a 32-bit download).

I now have the following view on the configuration page:

However, I'm seeing the following on the RStudio Console:

And I'm seeing the following on the Troubleshoot page:

What else should I do to remedy this? Thank you.
