    Hi Samuel Terkper Ahuno,

    Happy to hear you were able to run your workflows successfully! We are seeing big improvements, with many users and internal folks no longer running into this issue. We will update the article to mark it as fully resolved after some final checks.

    Kind regards,

    I think it's now resolved, I run workflows paired-fastq-to-ubam, preprocessing for variant discovery and haplotype-caller on WES 216 samples yesterday evening without any errors (except user input errors from my side). can someone else check to confirm?

    Hi Jason, 

    I'm getting a similar error now: "GcsBatchFlow.BatchFailedException: Error writing request body to server". 

    It fails in a task upon trying to estimate size(my_input_bam) before the command section.
