This works for me using the latest quantmod on CRAN (0.4.21). Can you please provide the output from sessionInfo()?

It's really weird but I always get the same error.

UPDATE:

got the 0.4.20 version from github and with that it still works

UPDATE END Seems to be the same error to me

if(!require('quantmod')) {
  install.packages('quantmod')
  library('quantmod')
}

TSLA = getSymbols("TSLA")

Thanks for the info. Can you provide the output of packageDescription("jsonlite")?

If that returns NA and throws a warning about jsonlite not found, can you try again after installing the quantmod version on branch 380-import-jsonlite?

You can install it with remotes::install_github("joshuaulrich/quantmod@380-import-jsonlite")

It works after installing 380-import-jsonlite . Thank you very much!!

Description: A reasonably fast JSON parser and generator, optimized for statistical
         data and the web. Offers simple, flexible tools for working with JSON in
         R, and is particularly powerful for building pipelines and interacting
         with a web API.  The implementation is based on the mapping described in
         the vignette (Ooms, 2014).  In addition to converting JSON data from/to R
         objects, 'jsonlite' contains functions to stream, validate, and prettify
         JSON data. The unit tests included with the package verify that all edge
         cases are encoded and decoded consistently for use with dynamic data in
         systems and applications.
