Hi there @alizasnow,

I guess you are showing output from Table View node and missing value under scores column is troubling you? Well where did missing value first appeared? That is the node you should check…

Hi @alizasnow -

So I gather this is the workflow referenced in the blog post by @craigcullum (https://www.knime.com/blog/will-they-blend-today-twitter-and-azure-sentiment-analysis-via-api).

As @ipazin said, can you look carefully at the outputs of each node and see where the score is being returned missing? If it’s null coming out of the POST Request node, it’s possible something has changed on the Azure side since this blog post was written.
