Hi @kenchan0130 - Thanks for this PR. I believe that URL encoding the data could leave to regressions elsewhere. Shell incompatible characters in IDs can be catered for by simply enclosing the ID in " as below. If you can update the doc with the suggestion and revert the code changes, I can this merged.

Thanks

URL / shell incompatible encoding can be supported by quoting the import line on the cli, such as:

Suggested change

	terraform import azuread_application_identifier_uri.example /applications/00000000-0000-0000-0000-000000000000/identifierUris/aHR0cHM6Ly9leGFtcGxlLm5ldC8%3D
	terraform import azuread_application_identifier_uri.example "/applications/00000000-0000-0000-0000-000000000000/identifierUris/aHR0cHM6Ly9leGFtcGxlLm5ldC8="

This differs from my understanding.
The core issue lies in the fact that the following call does not account for the possibility that the base64-encoded string may contain the / character:

• https://github.com/hashicorp/terraform-provider-azuread/blob/main/internal/services/applications/application_identifier_uri_resource.go#L136
• https://github.com/hashicorp/terraform-provider-azuread/blob/main/internal/services/applications/parse/from_template.go#L30

Even when using the import block, the same error described in issue #1691 still occurs.

Therefore, this is not a shell-related issue.
