Why Am I Getting an Error When Querying Ssm Parameters via Get-Parameters-by-Path?
I Am Trying to Query Some Ssm Parameters by Path (Within Gitbash): Aws --Region Eu-West-2 --Profile Some-Profile Ssm Get-Parameters-by-Path --Path...
I am trying to query some SSM parameters by path (within Gitbash):
aws --region eu-west-2 --profile some-profile ssm get-parameters-by-path --path /prefix/prefix2
There are a number of parameters that exist which match this prefix, e.g.
/prefix/prefix2/p1
/prefix/prefix2/p2
...
I am getting the following error back:
An error occurred (ValidationException) when calling the GetParametersByPath operation: The parameter doesn't meet the parameter name requirements. The parameter name must begin with a forward slash "/". It can't be prefixed with "aws" or "ssm" (case-insensitive). It must use only letters, numbers, or the following symbols: . (period), - (hyphen), _ (underscore). Special characters are not allowed. All sub-paths, if specified, must use the forward slash symbol "/". Valid example: /get/parameters2-/by1./path0_.
I get the same error if the prefixes end in "/". What is the cause of the problem?

If you're using MSYS-based bash on Windows, make sure you prefix with MSYS2_ARG_CONV_EXCL=* to prevent it from expanding /prefix/prefix2 to a windows path.
If you are using a Windows based command use:
aws ssm get-parameters-by-path --path '//dev//another//path'
(Double slash)
That solved my issue on Windows.
For windows Git Bash, You need to use MSYS2_ARG_CONV_EXCL="*" in Environemnt variable (like mentioned by @Dylan Nicholson), or just use export as below
The exact code needed is as below
export MSYS2_ARG_CONV_EXCL="*"
after that you can call the command normally as below
aws ssm describe-parameters --parameter-filters "Key=Name,Values=/dev/another/path"
