Transcy - What is error with Value fails validation on resource ["Value must be a single line text string."]

You might find this error in the app when trying to edit the translation of metafields but can't save.

The reason behind is because your default metafields are set wrongly as single line instead of multi lines in Shopify setting.


You set this metafield as single line but it must be the multi lines type of metafields

So it does not work and generate the above error message. To resolve it, please help me edit the type "single line text...." into "multiple_line_text_field" in Shopify setting.

Shopify setting >> Custom data

Then you can edit the translation of metafields normally in the app.

Hope this help you a lot!
