Current Behavior

When trying to update a SSM parameter with an empty string (with PutParameter), the following error occurs:
1 validation error detected: Value '' at 'value' failed to satisfy constraint: Member must have length greater than or equal to 1.

Expected Behavior

We should be able to set a SSM parameter value to an empty string

Thanks for reporting @yonatandbinahai - just to confirm, have you been able to get this resolved in the meantime, or does the problem persist with the latest image? Thanks!

@whummer sorry, it was a mistake, apparently AWS SSM doesn't allow storing empty values either, so works as expected.
