Rpubs upload error

I receive this error when I try to upload a flexdashboard which is rendered properly in rStudio:

Error in rawToChar(response$headers) : argument 'x' must be a raw vector
Calls: ... http -> -> grep -> parse_headers -> rawToChar
Execution halted

This started after I createad a shiny app inside this same project. Even though I removed the shiny code it still can't upload.

Please help, this site is the hospital bed occupation for COVID 19 in a 1.4 million people city in Brazil.
Thanks,
