I found the root cause of this issue.
In my case, i were using CRM data source(custom entity record). In these record one of the field has "appres://blobmanager/548ff7b0eef6441c8b8bbbc6f8fd3afe/105" data which is BLOB data generated by PenInput control and saved by patch request from powerapps.
if i removed the field from collection or removed this blob data then this issue gets disapeared.
hope this helps.
