importing to node-red returns error of data type

[HaliSyed]

Following all steps and model is populated properly but while doing test run it returns error

Error 400 An exception occurred during Scoring with message: Value for field name COLUMN2 with datatype ScalarType(string,true) is incorrect.

[chughts]

Which test where you running? The hard coded test?

[HaliSyed]

No the first one run prediction

Error 400 An exception occurred during Scoring with message: Value for field name COLUMN2 with datatype ScalarType(string,true) is incorrect.

[chughts]

Please elaborate on 'No the first one run prediction' which test exactly.

[HaliSyed]

Please accept apology,
I mean on the first step you run the hardcode test which is where you modify run prediction and provide credentials and select the model created on watson studio project

[chughts]

If you haven't modified the node with the hard-coded test then it will be building a test for the payload as below. All the columns are floating point / decimal numbers. It looks like you have created a model where column2, and I guess all the others, is a string. Check your data, and ensure that the model builder is picking up the columns as numbers and not strings.
