We have a situation where a previously running correctly Azure Synapse Link for Dataverse configuration was removed.
In trying to re-establish this configuration, we are following our documentation that was used to establish this in the first place, and even allowing for the updated Microsoft documentation that suggests that Azure Synapse Pipelines need to use trigger().outputs.body.folderPath expression instead of what we previously used as triggerBody().folderPath to obtain the container and folder values for the file triggering the pipeline.
In trying this we are encountering a "filesystem does not match expected pattern" error with values in the error message for FileSystem and Folder path that look like the literal values of the expressions that are specified in the pipeline Trigger Run Parameters. So it doesn't look like the expressions are being evaluated. We have tested this further by specifying Default values for the parameters, which also look like expressions are not being evaluated.
So my question is. do Parameters Default Values support expressions? Is there a way we can examine what the values being assigned to the "container" and "folder" parameters of the DataverseToSQL pipeline at run-time?
