## Describe the problem/error/question Getting frequent errors in the Mautic node. Even running a retry does not resolve the error. ## What is the error message (if any)? There are 2 different messages I am getting: Error: Bad request - please check your parameters Stack: NodeApiError: Bad request - please check your parameters at Object.mauticApiRequest (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-nodes-base/dist/nodes/Mautic/GenericFunctions.js:37:15) at runMicrotasks () at processTicksAndRejections (node:internal/process/task\_queues:96:5) at Object.execute (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-nodes-base/dist/nodes/Mautic/Mautic.node.js:653:44) at Workflow.runNode (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-workflow/dist/Workflow.js:653:28) at /usr/local/lib/node\_modules/n8n/node\_modules/n8n-core/dist/WorkflowExecute.js:592:53 Some other times I get: Error: Cannot convert undefined or null to object Stack: TypeError: Cannot convert undefined or null to object at Function.values () at Object.execute (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-nodes-base/dist/nodes/Mautic/Mautic.node.js:658:51) at runMicrotasks () at processTicksAndRejections (node:internal/process/task\_queues:96:5) at Workflow.runNode (/usr/local/lib/node\_modules/n8n/node\_modules/n8n-workflow/dist/Workflow.js:653:28) at /usr/local/lib/node\_modules/n8n/node\_modules/n8n-core/dist/WorkflowExecute.js:592:53 ## Please share your workflow ## Share the output returned by the last node ## Information on your n8n setup - \*\*n8n version: 0.224.4 - \*\*Database (default: SQLite): Postgres - **n8n EXECUTIONS\_PROCESS setting (default: own, main):** queue - **Running n8n via (Docker, npm, n8n cloud, desktop app):** docker - **Operating system:** debian ---

Hi @Martin_Neumann, I am sorry you’re having trouble. Seeing this happens frequently (but not always) I wonder if this depends on your specific input data. Can you confirm which data exactly your webhook node is passing on when running into these errors? ---

I got it resolved by setting up a new n8n instance and renewing the credentials. But it is really strange. When I migrate my Mautic to a different VPS, I almost always have some problems to get it work with n8n. Even resubmitting the Oauth authorization or creating a new credential in Mautic does not resolve it. Sometimes I manage to resolve it by deleting the credential in n8n and creating a new credential. And seems that others had the same problem. Is it possible that something gets messed up in the credentials when you change the IP of the Mautic instance? ---

Hey @Martin_Neumann, That is possible, creating a new credential / oauth app in Mautic should solve the issue though if the client id / client secret changes during migration though. ---

unfortunately no. I had to delete the credential in n8n and define a new one, and then update all the workflows. That is normally the way to get it back working. Defining a new credential in Mautic is not resolving the issue after doing a Mautic migration. ---

Recreating the credential would do it as well if the new instance isn’t able to handle the token for whatever reason. It is a bit odd but sounds like something that could be expected. ---
