I am a software developer who is currently working on an AWS project. While trying to create a new role, I keep facing the same problem. Whenever I try to create a new IAM role with a certain policy document, AWS CloudFormation throws an error message stating that the ‘createRole’ action has a prohibited field.
Here is the code I am using to create the role:
Resources:
myRole:
Type: 'AWS::IAM::Role'
Properties:
RoleName: 'myRole'
AssumeRolePolicyDocument:
Statement:
- Effect: Allow
Principal:
Service:
- ec2.amazonaws.com
Action:
- 'sts:AssumeRole'
ManagedPolicyArns:
- arn:aws:iam::aws:policy/AmazonS3FullAccess
- arn:aws:iam::aws:policy/AmazonEC2FullAccess
Policies:
- PolicyName: 'myPolicy'
PolicyDocument:
Statement:
- Effect: Allow
Action: ['ec2:StartInstances']
Resource: ['arn:aws:ec2:*:*:instance/*']
What could be causing this error message? I have tried various ways to change the policy document, but I still get the same error. Is there something wrong with my IAM role creation syntax? Any help would be much appreciated.

Hello there! I see you’re having some challenges with AWS and the prohibited field error when creating a role. Well, I completely understand how frustrating it can be to face such obstacles, but don’t worry, I’ve got you covered!
The prohibited field error you’re experiencing when trying to create a role in AWS usually occurs when you’re attempting to set a value for a field that’s not allowed to be set. This can be particularly confusing if you’re not entirely sure which fields are prohibited or how to go about fixing the error.
To resolve this issue, the first step is to check the documentation to be sure of the fields you’re allowed to set for the AWS role you’re creating. AWS IAM can be particularly sensitive to the values passed in its requests. Ensure that you have passed the right values and data types for each field.
If the issue persists, then you should cross-check to verify that all the required parameters are specified correctly. Some of these parameters include role name, path, assume role policy, and access control policy. It is important to note that if any of these parameters are missing or specified wrongly, AWS would throw the prohibited field error.
Another way to troubleshoot this error is by checking your credentials. Ensure that you’re properly authenticated by AWS and have the necessary permissions to perform the operation you’re trying to carry out. If you’re working with APIs, you might want to check the format and structure of the JSON you are passing to ensure that it is the correct one for creating an IAM role.
Finally, you may also want to check that you are using the latest SDK for your programming language. AWS frequently makes updates and changes to their services and SDKs to enhance their functionality and security features. If you’re using an outdated SDK or version, you may encounter errors that have been fixed in the latest versions.
I hope these tips are helpful in resolving your prohibited field error when creating a role on AWS. Keep on coding, and have fun!
You can’t create a role with a prohibited field. You need to make sure that the fields you are using to create your role are allowed by AWS policies. To do this, consult the AWS documentation for the specific service you are using, such as IAM or S3. In some cases, you may need to provide additional permissions or configure settings to allow the use of certain fields. Double check that you are using valid syntax and that any required fields are provided.
From my own experience, I’ve found that AWS error messages can be dense and frustrating, but sticking with the documentation and troubleshooting step-by-step can help to resolve issues. Don’t be afraid to reach out to the AWS support team or consult the AWS community forums for guidance. They can be a valuable resource for finding solutions to specific problems.
One possible solution to the problem you are facing with creating a role that has prohibited fields is to modify the policy of the IAM user that you are working with. You may need to add the necessary permissions to the user’s policy in order to create a role with the required fields. You can do this by accessing the IAM console and navigating to the permissions tab of the user you are using. From there, you can add the necessary permissions for role creation.
Another possible solution is to use the AWS command line interface (CLI) to create the role. You can use the `aws iam create-role` command to create a role and specify the necessary fields. This will give you more control over the creation of the role and allow you to bypass any restrictions that may be in place via the AWS Management Console. If you are unsure of how to use the AWS CLI, there are plenty of resources available online to help you get started.
Ultimately, it is important to make sure that you have the necessary permissions and access to create the role in question. This may require modifying the policies of the IAM user that you are working with, or using the AWS CLI to bypass any restrictions that may be in place. With the right approach, however, you should be able to successfully create the role you need for your project.
In order to use AWS create role to its full potential, there are a few things to keep in mind. One important thing is to make sure that the policy you are creating is correct and specific enough for your needs. You can encounter a prohibited field while creating a policy, and you should know that there are some restrictions in place for AWS policies. These restrictions are there to prevent the user from creating policies that could be unsafe or conflict with other policies that are already in effect.
In some cases, you might not be able to create the policy the way you want to, due to these restrictions. However, this doesn’t mean that you can’t find an alternative solution that will work for your needs. You can try to rephrase the policy or create multiple policies that work together to achieve your desired outcome. Another way to approach this issue is to try using a different AWS service that might not have the same restrictions in place, and that could help you achieve what you want to accomplish.
Overall, when using AWS create role, it’s important to have a good understanding of the various policies and restrictions that are in place. While it can be frustrating to come across a situation where you are unable to create the policy you want, there are usually alternative solutions that can be used instead. By keeping an open mind and exploring various options, you can find a solution that will work for you without compromising on security or safety.
