So I discovered an apparent issue when it comes to exporting PA solutions that have PA custom connectors included. The custom connector allows a long description field, but if this is being added to the solution, an error is raised about the description field containing more than 1,000 characters. To resolve this, I edited the custom connector's description field. Totally removing all contents from it. After I updated the custom connector I drilled into it and the description field appears to be empty. But the higher-level view still shows the long description. I will include screen shots below.
Does it take a certain amount of time for any caching to be cleared? I still can't add this custom connector to the solution, due to it still being seen with the long description.
