Good afternoon, I have a problem when sending a message from b4a, it shows me a 401 error, where it does not allow me to obtain the token.
In B4J I have no problem sending a message, it reaches its destination correctly.
I attach the error that it displays, as well as the modules that I use to send a message. I download the DirAssets json file to DirInternal and check its existence, but for some reason it does not detect it.
This is the error
Finally, I verify that the json file is indeed located in DirInternal.
Any help, thanks!!
