Hi Alma,
It seems like you are encountering an issue while trying to set the value of stream 'PFD136' to 'flow_136'. The error message "Invoke error. Dispatch exception. Access is denied" indicates that there might be a permission or authorization problem with the operation you are trying to perform.
To troubleshoot this issue, you can start by checking the syntax of your code or command to ensure that it is correctly formatted and follows the expected structure for setting values to streams. Make sure that you have the necessary permissions and access rights to modify the stream 'PFD136' in your system.
If the syntax error persists, you may need to review the documentation or guidelines provided by the platform or software you are using to interact with streams and data sources.
Additionally, consider reaching out to technical support or consulting online resources for further assistance in resolving this error. It's important to address any access restrictions or authentication issues that may be causing the denial of access to perform the desired operation.
By verifying your permissions, revising the syntax of your code, and seeking help from relevant resources, you can work towards resolving this problem and successfully setting the value of stream 'PFD136' to 'flow_136'.

Could it be you want to write 'kg/s' instead of "kg/s"?
