Embedding API Post Input is Array insted of String

[ddahmhenderson]

Im am trying to add https://docs.ionos.com/cloud/ai/ai-model-hub/tutorials/text-embeddings from the provider Ionos. Ionos say the API is modeld after an generic OpenAI API. Still the embedding gets an error:
"rag_api | 2024-12-08 21:21:16,858 - root - ERROR - JSON format issue: expected string at field input got instead array"
Please fix or telle me how to fix it.
Thank you!
