Question

In the past two days, our pipeline has encountered errors several times during its operation. We need the support of Microsoft. The pipeline mainly retrieves data from the Synapse link and writes it to the VM service. We haven't been able to find the cause of the errors. Our pipeline runs in East Asia. Could you please help check it out? The error messages are as follows:
