I tried converting it to float. I still get a similar error.
Hi vijay reddy
I am also looking for some help. I am tableau server administrator and my desktop users asking for web data connectors. I know its all on local machine where they will develop their web connectors.
I want to know is there anything needs to be done at Tableau server end in order to allow workbook rendering those are based on web data connectors?
Any help would be much appreciated.
If the requirement is to publish the tableau documents created using webdata connector to the server and be able to refresh/schedule them then yes there are certain things that needs to be done on the tableau server
1. you will need to whitelist the web data connector urls
tabadmin whitelist_webdataconnector -a https://example.com/myconnector.html
tabadmin whitelist_webdataconnector -s https://example.com/myconnector.html https://myFirstAPI.com/getData,http://mySecondAPI.com:80/(.*),data:image/(.*)
more information can be found at tabadmin commands
2. For refreshing the extract in tableau server, you need to make sure the password is embedded in the tableau document while publishing.
depending on the authentication type of the web data connector, the developer would need to store either the user name and password(for basic authentication ) or accesstoken(for oauth)
