Hi @Valeriia !
I’m not too familiar with the language that you’re using. I may be too late and way off, but I thought I’d throw it in here anyway just in case it’s helpful.
I wonder if this is the same problem that @supernova faced in Can't change column value(s)
I see
value_json<-toJSON("{'index':3}")
request_form<-paste(
'mutation {change_column_value (
board_id: 347384734,
item_id: 34239483,
column_id: "status",
value:',value_json,' ) {
id
}
}',sep = '')
And that made me wonder if you’re plugging your value straight into the query. In the above post mentioned, we discovered that there’s a problem with that query and variables is required for change_column_value.
Hope that helps
