Set clipboard content not working

Set clipboard content is not working normally, in compiling and testing the app, in the browser version everything works, but on android it doesn’t work.
I added 2 clipboard elements, 1 works and one doesn’t

The value that doesn’t copy is json appVars.pagarboletobtc.“BTC”

my problem was fixed, i forgot to convert string value to text STRING(appVars.valorconverterbtc)
