I have a problem with a GET node in KNIME. I have a query which includes parameter, and somehow KNIME does not accept how I put in the parameter value. In short, i have a query (it’s a REST interface of a DB) which ist like
URI?param=[Filter]{TableName:TEST,ColumnName:col,Filter:“Great”}
and the error I get is
Execute failed: Unresolved variables; only 0 value(s) given for 1 unique variable(s)
To me it seems, that “[Filter]{TableName:TEST,ColumnName:col,Filter:“Great”}” is not accepted as value.
However, the same query in Postman works without any problems…
If i delete the filter parameter the query works, are there constraints on the input of parameter values?
Any help?
Thanks!
