"Java Exception <no description because toString() failed" error in shiny appication

[nahmadi69]

Dear colleagues,

I’m Naser. I attempted to use the "xlsx" package to upload my password-protected Excel file. It works locally, but when I deployed it on shinyapps.io, I encountered an error possibly related to rJava or the Shiny servers. After contacting Posit, I decided to reach out to you.

Error: An error occurred: Java Exception <no description because toString() failed> loadWorkbook(file, password = password) new("jobjRef", jobj = <pointer: 0x5ad06c9f9008>, jclass = "java/lang/Throwable")

Deployed app: https://naser-ahmadi.shinyapps.io/Payment-warning App username: "1", password: "1"

I would appreciate your assistance in resolving this issue, and I look forward to your response.

Best,
Naser
