Hello @Deba Nayak ,
Thanks for the question and using MS Q&A platform.
I suspect something could be wrong with dataset parameters configuration. I just tried a sample in my ADF and it is working for parameterized REST connector. Could you please make sure your configuration is similar to below:
**Mapping Dataset Parameters to REST Linked Service parameters: **
Mapping incoming baseURL and relativeURL value dynamically from pipeline parameters to REST Connector dataset parameters which we configured in earlier steps:
For debugging you will have to pass the hardcoded
relativeURL from Debug Setting as below and then do data preview in your source transformation.
Sample Data Preview looks like below:
Could you please verify your configuration by following above series of steps and let us know if that helps to resolve your issue.
