Hello everyone,

I'm encountering an issue while trying to translate a Word document from English to Spanish using the OpenAI translation plugin for Trados. The plugin works perfectly for smaller projects and even worked once with this particular file, but now it has stopped functioning.

Problem Details:

• The document contains a lot of tags , including a table of contents with links.
• The file opens without any issues and is translatable line by line, the NMT is also working line by line.
• The main problem arises when I attempt to run the batch task to pre-translate the file using Neural Machine Translation (NMT).
• I receive the following error message when running the batch task:

Error Message: [ Only Exception type is allowed ]

• I have also checked the OpenAI log (attached below), and it seems there's no data sending back.
• API has charged the usage.

Steps I've Tried:

• Verified that the plugin works with other smaller projects(plain words).
• reinstalled the Trados2024
• Restarted Trados and my computer.
• Checked my internet connection to ensure it's stable.
• Reviewed the plugin settings to confirm they're correctly configured.
• I have tried all different configeration(including change the 

Request:

Has anyone experienced a similar issue or have any suggestions on how to fix this problem? Any insights or solutions would be greatly appreciated.

Thank you in advance for your assistance!
