Most Common 2nd Generation Package Errors

Dear valued readers,

As you may already know, Salesforce has released its second generation package manager, also known as 2GP, in 2017. This package manager has been designed to help developers create and manage packages in a more efficient and streamlined way, making it easier for them to build and distribute their apps on the Salesforce platform.

While 2GP offers many benefits to developers, there are some common errors that they may encounter during the development and packaging process. In this newsletter, we will take a closer look at some of the most common errors faced by developers when using the 2GP, along with their reasons.

1. Error: "Package version must be created from a non-source-tracked org"

This error occurs when developers attempt to create a package version from an org that has source tracking enabled. In order to avoid this error, developers should create a new scratch org without source tracking enabled and then create the package version from this new org.

2. Error: "Failed to retrieve the package dependencies"

This error is usually caused by missing or incorrect dependencies in the package. To fix this error, developers should double-check their package dependencies and ensure that they are correctly specified in the package manifest file.

3. Error: "Too many Apex test executions"

This error occurs when developers exceed the maximum number of Apex test executions allowed in a 24-hour period. To avoid this error, developers should ensure that they are only running the necessary tests and that they are running them in batches to avoid exceeding the limit.

4. Error: "Invalid Package Version Configuration"

This error can occur when developers have not configured their package version correctly. To avoid this error, developers should ensure that they have correctly specified their package version information, such as the package name, version number, and dependencies.

5. Error: "Package version creation failed"

This error can occur due to a variety of reasons, such as missing or incorrect dependencies, incorrect package version information, or issues with the packaging process itself. To troubleshoot this error, developers should carefully review their package manifest file and ensure that all dependencies are correctly specified, as well as checking their package version information for accuracy.

6. Error: "Failed to install package"

This error occurs when you try to install a package, but the installation fails due to various reasons, such as a missing dependency or conflict with an existing package. To resolve this error, you need to identify the root cause of the failure and address it accordingly.

7. Error: "The package version is not compatible with the target org"

This error occurs when you try to install a package version that is not compatible with the target org's API version or edition. To resolve this error, you need to either upgrade the target org's API version or choose a compatible package version.

8. Error: "Invalid package version"

This error occurs when you try to create or install a package version that has invalid metadata or dependencies. To resolve this error, you need to review and correct the metadata or dependencies of the package version.

9. Error: "Package upload failed"

This error occurs when you try to upload a package version, but the upload fails due to various reasons, such as a network connection issue or an invalid package file. To resolve this error, you need to check your network connection and ensure that the package file is valid.

10. Error: "Dependency cycle detected"

This error occurs when you try to create or install a package version that has a circular dependency, which means that two or more packages depend on each other. To resolve this error, you need to identify and break the circular dependency between the packages.

While these errors may seem daunting at first, they are all easily fixable with a little bit of troubleshooting and attention to detail. With the 2GP, developers now have a powerful tool at their disposal that allows them to create and manage packages with greater ease and efficiency, helping them to build better apps and achieve greater success on the Salesforce platform.

We hope that this newsletter has been helpful in shedding some light on the most common errors faced by developers when using the 2GP, and that it has given you a better understanding of how to avoid and troubleshoot these issues. As always, we encourage you to stay up-to-date with the latest Salesforce news and updates, and to continue exploring the many exciting opportunities that the platform has to offer.
