No revision URL or commit hash resolved

[desoss]

Is there anything I should do to stop receiving the error No revision URL or commit hash resolved?

This is my pipeline:

import {CodeBuildAction, GitHubSourceAction, GitHubTrigger, S3DeployAction} from "aws-cdk-lib/aws-codepipeline-actions";

.... 

    const pipelineActions = 
          {
            source: new GitHubSourceAction({
                actionName: 'Github',
                owner: repoProps.owner,
                repo: repoProps.name,
                branch: repoProps.branch || "master",
                oauthToken: secret.secretValue,
                output: artifacts.source,
                trigger: GitHubTrigger.WEBHOOK,
            }),
            build: new CodeBuildAction({
                actionName: 'CodeBuild',
                project,
                input: artifacts.source,
                outputs: [artifacts.build],
            }),
            deploy: new S3DeployAction({
                actionName: 'S3Deploy',
                bucket: props.bucket,
                input: artifacts.build,
            }),
            invalidate: new CodeBuildAction(
                {
                    actionName: 'InvalidateCache',
                    project: this.getProjectForInvalidateCloudFront(props.domain, props.distribution),
                    input: artifacts.build,
                }
            )
        };

        const pipeline = new Pipeline(this, formatDomain(props.domain) + '-pipeline', {
            pipelineName:  `pipeline`,
            stages: [
                {stageName: 'Source', actions: [pipelineActions.source]},
                {stageName: 'Build', actions: [pipelineActions.build]},
                {stageName: 'Deploy', actions: [pipelineActions.deploy]},
                {stageName: 'InvalidateCache', actions: [pipelineActions.invalidate]},
            ],
        });
