Hi,
I'm developing in EpiServer CMS version 9.12.2.0 as an IT consultant for a customer that we have.
We are having a problem after deploying into production, where this SQL error (see attachment below) appears when our customer is trying to edit pages in the CMS.
Everything seems to work fine locally, however, after deploying to production this error will sometimes appear. As a temporary solution this can (sometimes) be solved by doing a redeploy, but we are unsure why.
We could do simple changes, like adding a single property to a page type. Then after deploying, when our customer tries to edit the input field for this new property, this error appears before publishing can be done. This can happen to multiple pagetypes and there are no issues with the code.
We also tried to change and rename the properties used, but this doesn't solve the problem.
Any ideas (except for updating the CMS and keep redeploying) for what we can do here? Maybe someone have some more information about this issue and why it happens, and in what version it eventually was solved?
