I am using a global parameter in the pipeline as shown below:
I created a tumbling window trigger which triggers the pipeline 5 times parallelly. The issue is few trigger runs are able to capture the value in global parameters and few are not. Can you please look into this issue. Its the same pipeline and same trigger.

As shown it worked for 3 with the same global paremeter and failed for 2 with the below error :
Operation on target getmetadata_frm_azblob_folder failed: The expression 'pipeline().globalParameters.adls2_container' cannot be evaluated because property 'adls2_container' doesn't exist, available properties are ''.
