Im trying to upload the image files to s3 by spring boot api call using http request legacy activity in UiPath, the files are uploaded to s3 successfully. But after this activity i used deserialize json activity to get the api response, I created a variable store the response of the api request and put it in the http request legacy activity’s response content field in the properties panel. after the http call activity complete, my deserialize json activity is returning this error.

Deserialize JSON Array: Value cannot be null. (Parameter ‘s’)

Can anyone help me to resolve this?

Hi @Prabhakaran_Elango

Any reason why you are using the legacy activity instead of the new one? I’d like to learn that first, because the new one should work better in practically every aspects.

As to this issue, could you please post a couple more screenshots how you configured the variable and how you are passing it to the next activity?
