Dev Gateway fails with error Invalid Parameter

[norelina]

When trying to run the Dev Gateway, all of a sudden it has started failing with the following error and message: All strings must be between 5 and 2000 characters long:

Thank you for reaching out. The issue you're encountering is due to a new enforcement we've recently implemented, which requires all strings to be between 5 and 2000 characters long. However, I want to let you know that this minimum value is planned to be adjusted to 3 characters next week.

In the meantime, feel free to provide any additional information if needed, and we’ll be happy to assist with further troubleshooting.

Any ETA for this? Still fails.

Hello @dhrumil83, we were able to resolve this issue on our side by adjusting the length of the displayName and the productDetail/publisher values in our Product.json file. The latest in the sample repo has a validation script that can be used to check on that (e.g., by running node validation/validateSchema.js)
