Behavior of non required text fields when update

[dcarracedo]

Description In the form text fields, when you're trying to delete a value after having a template that has a value in this field, an error is showed if the field is empty, you need to add a value even the field is not required. For example, if you create a template with a volatile disk that has the field Total values of Throttling (Bytes/s) section and you try to update this template, the form shows an error when the field is empty.

To Reproduce

1. Create a template with a volatile disk that has the field Total values of Throttling (Bytes/s) with any value (e.g. 1)
2. After created it, update the template and edit the disk. Delete the value fo the field Total values of Throttling (Bytes/s) and click Finish.
3. An error appears saying that this field has to have a number.

Expected behavior That is a field is non required, the user could click on the Finish button and finish the form without errors when the field is empty.

Also, this problem is in all the text fields that are not required, not only in the volatile form disk.

A possible solution it's transform the value: { name: 'TOTAL_BYTES_SEC', label: T.TotalValue, type: INPUT_TYPES.TEXT, htmlType: 'number', notOnHypervisors: [lxc, firecracker, vcenter], validation: number() .min(0) .transform((value, originalValue) => originalValue && originalValue?.trim() === '' ? undefined : value ) .notRequired() .default(() => undefined), },

This could be added in a generic way in the TextController but checking that the required fields still working. If not, we need to check the schemas to add this transform function.
