If you are trying to convert the data type of topics going through the OPC UA server and have issues with viewing the data (you see `null` values), keep in  mind the following:

- The OPC UA server can't convert data types of topics
- The OPC UA server will work with the original data types coming from the topic

## Solution: Parse Data before Sending to OPC UA Server

To resolve this issue, you will need to create a custom OPC UA custom tag by creating a JSON object and sending it to the appropriate topic. 

Refer to the following to learn more:

- [Mozilla Developer Documentation - parseint()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt)
- [Data Type Mapping](docId\:kcIK3t2IxCTWmcdrgYIbk)

You can also review the following JSON file example that creates a flow to convert the data type of data before sending it to the OPC UA Server. See [Manage the Flow Canvas](docId\:DCwt2Tl7ue0KOS1RsiaBf) to learn more about importing JSON files.
