Error creating journal transaction. Customer currency and Base currency are Identical

[Quan Pham]

Hi,

I'm encountering an error when trying to create a journal transaction with the JSON below. The same JSON works in another company but fails in this one.

If I remove the "exchangeRate" field, it works, but it should be possible to send a value of 0 since it works for another company. Could you help me understand why this is happening and how to fix it?

Thank you!
