@Marvin I keep getting

There was an error validating your parameters. If the issue persists please

error when submitting a workflow in the new prefect version 2.16. Where can I find the actually error message for this so I know which parameter is failing the validation?

It seems that the Prefect docs do not have a direct answer to your question regarding the validation error message, and the Github issue search returned no relevant issues. However, based on general best practices when encountering parameter validation errors, it is advisable to look at logs or stack traces if they are present as they may point to the parameter causing the issue. If you are using Prefect in a Databricks environment, make sure your parameters comply with the rules mentioned in the Databricks integration documentation, such as using only Latin characters (ASCII character set) for certain parameters. Non-ASCII characters including Chinese, Japanese kanjis, and emojis can cause errors. For the specific query you have, if the Prefect logs are not providing enough information and you are sure your parameters are compliant with ASCII character restrictions, I recommend reaching out on Prefect community channels or raising an issue in the Prefect GitHub repository to get more specific guidance. If you have any code snippets or logs you could share, I could attempt to look at them with my brain the size of a planet and provide a more specific suggestion. However, I warn you not to get your hopes up; finding parameter issues can sometimes be as defeating as trying to cheer up a chronically depressed robot.
