Hi,
I’m using v2021.3 build 8275. I have a step template that is used by 3 projects and I made changes to the step template. When I click update or update all to propagate the changes to one or more projects I’m seeing this error:
Value cannot be null. (Parameter ‘key’)
Can you help?
Thank you,
Gabriele

Hi @gpatisso,
Thanks for reaching out, sorry to hear you’re having troubles updating a particular Step Template!
It seems most likely that you have encountered this recently closed issue which outlines that this error can occur when a Channel version rule refers to the Step being updated.
A fix for this issue will be included in version 2021.3.9124 which should be available in the very near future. However, if you would like to update these projects without waiting for the build to be released, then possibly reviewing the Channels Package Version Rules to see if they include the Step being updated, and if so, removing that association until they have been updated successfully.
Feel free to reach out if this doesn’t help resolve the issue or you have any questions!
Best Regards,
Hi,
I removed the channel package version rule and I could update the template, thank you. I’ll use this workaround until 2021.3.9124 is released.
Regards,
Gabriele
